Subject: pgsql: Convert buffer manager to use the new shmem allocation functions
Date: Sun, 05 Apr 2026 23:27:44 +0000
Message-ID: <E1w9WsZ-0039AL-1A@gemulon.postgresql.org> (raw)
Convert buffer manager to use the new shmem allocation functions
This rectifies the initialization functions a little, making the
"buffer strategy" stuff in freelist.c and buffer mapping hash table in
buf_init.c top-level "subsystems" of their own, registered directly in
subsystemlist.h. Previously they were called indirectly from
BufferManagerShmemInit() and BufferManagerShmemSize()
