Subject: pgsql: Introduce a registry of built-in shmem subsystems
Date: Sun, 05 Apr 2026 23:27:43 +0000
Message-ID: <E1w9WsZ-00399z-0J@gemulon.postgresql.org> (raw)
Introduce a registry of built-in shmem subsystems
To add a new built-in subsystem, add it to subsystemslist.h. That
hooks up its shmem callbacks so that they get called at the right
times during postmaster startup. For now this is unused, but will
replace the current SubsystemShmemSize() and SubsystemShmemInit()
calls in the next commits.
