* [PATCH v52 07/10] Check for transaction block early in ExecRepack

Currently, executing REPACK (CONCURRENTLY) without a table name inside a
transaction block throws the error "REPACK CONCURRENTLY requires explicit
table name" instead of the expected transaction block error. This occurs
because ExecRepack() validates the parsed options and missing relation
before verifying the transaction state.

This behavior is inconsistent with other utility commands like VACUUM
,REINDEX, etc; which invoke PreventInTransactionBlock() at the very start
of their execution to properly reject execution inside user transactions
before validating targets.

Add PreventInTransactionBlock to the top of ExecRepack() to enforce the
transaction block restriction early. This prevents the user from fixing
a missing table error only to immediately hit a transaction block error,
and also ensures consistency with rest of the commands.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.

* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.
