* [PATCH v33 08/11] Add aggregates support in IVM
@ 2023-05-31 11:46 Yugo Nagata <[email protected]>

From: Yugo Nagata @ 2023-05-31 11:46 UTC (permalink / raw)

count, sum, adn avg are supported.

As a restriction, expressions specified in GROUP BY must appear in
the target list because tuples to be updated in IMMV are identified
by using this group key. However, in the case of aggregates without
GROUP BY, there is only one tuple in the view, so keys are not uses
to identify tuples.

When creating a IMMV, in addition to __ivm_count column, some hidden
columns for each aggregate are added to the target list. For example,
names of these hidden columns are ivm_count_avg and ivm_sum_avg for
the average function, and so on.

When a base table is modified, the aggregated values and related
hidden columns are also updated as well as __ivm_count__. The
way of update depends the kind of aggregate function.=E3=80=80Specifically,
sum and count are updated by simply adding or subtracting delta value
calculated from delta tables. avg is updated by using values of sum
and count stored in views as hidden columns and deltas calculated
from delta tables.

About aggregate functions except "count()" (sum and avg), NULLs in input
values are ignored, and the result of aggegate should be NULL when no
rows are selected.  To support this specification, the numbers of non-NULL
input values are counted and stored in hidden columns. In the case of
count(), count(x) returns zero when no rows are selected, but count(*)
doesn't ignore NULL input.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional

set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 315+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.
