Subject: pgsql: Add regression test listing all the possible tuples in pg_stat_i
Date: Sat, 08 Mar 2025 03:24:36 +0000
Message-ID: <[email protected]> (raw)
Add regression test listing all the possible tuples in pg_stat_io
pg_stat_io returns a set of tuples based on a combination of three
properties (BackendType, IOObject and IOContext) and
pgstat_tracks_io_object() to decide if a BackendType should return a
tuple based on a pair made of an IOObject and an IOContext.
This commit adds a regression test to track all the combinations
supported. This is useful to know which tuples are relevant when adding
a new BackendType to the set or when touching pgstat_tracks_io_object(),
and I have noticed while playing with this area that it is not
complicated to break it without the regression tests noticing a
difference in some cases.
