* [PATCH v29 09/11] Add support for min/max aggregates for IVM
@ 2023-05-31 11:58 Yugo Nagata <[email protected]>
  0 siblings, 0 replies; 582+ messages in thread

From: Yugo Nagata @ 2023-05-31 11:58 UTC (permalink / raw)

Supporting min and max is more complicated than count, sum, or avg.

For an example of min, when tuples are inserted, the current min value
in the view and the min value in the inseteted tuples are compared,
then the smaller one is used as the latest min value. On the other
hand, when tuples are deleted, if the current min value in the view
equals to the min in the deleted tuples, we need re-computation the
latest min value from base tables. Otherwise, the current value in
the view remains.

* [PATCH v7 4/6] Handle pg_get_constraintdef default args in system_functions.sql
@ 2025-12-09 18:59 Mark Wong <[email protected]>
  0 siblings, 0 replies; 582+ messages in thread

From: Mark Wong @ 2025-12-09 18:59 UTC (permalink / raw)

Modernize pg_get_constraintdef to use proargdefaults to handle the
optional pretty argument.
