[PATCH v8 3/3] Use new overflow-aware integer comparison functions. 105+ messages / 2 participants [nested] [flat]
* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v8 3/3] Use new overflow-aware integer comparison functions. @ 2024-02-15 23:28 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 105+ messages in thread From: Nathan Bossart @ 2024-02-15 23:28 UTC (permalink / raw) Commit XXXXXXXXXX introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators, which helps ensure transitivity. The comparator functions that previously had trivial implementations (i.e., "if" statements) should also see a small performance boost.

* [PATCH v48 5/7] Fix a few problems in index build progress reporting. @ 2026-03-27 15:50 Ălvaro Herrera <alvherre@kurilemu.de> 0 siblings, 0 replies; 105+ messages in thread From: Ălvaro Herrera @ 2026-03-27 15:50 UTC (permalink / raw) First, index_build() should not update the progress when being driven by REPACK, because the progress reporting infractructure cannot handle status of two commands at the same time. So far, REPACK with the CONCURRENTLY option neglected this problem altogether, but even the existing REPACK wasn't consistent enough: even if the 'progress' variable in repack_index() was false, it didn't pass the value to index_build(). Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 6 files changed, 27 insertions(+), 8 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 38ef683d4c7..60fb7051830 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1183,7 +1183,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b86ad73c626..bac8d527ae5 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.
