Message-ID: <E1sm6Zr-000D9K-IC@gemulon.postgresql.org> (raw)
Add callback for backend initialization in pgstats
pgstat_initialize() is currently used by the WAL stats as a code path to
take some custom actions when a backend starts. A callback is added to
generalize the concept so as all stats kinds can do the same, for
builtin and custom kinds, if set.
