Subject: pgsql: Teach autoprewarm to use the dynamic shared memory registry.
Date: Fri, 19 Jan 2024 20:44:38 +0000
Message-ID: <E1rQvjC-002Chd-Cd@gemulon.postgresql.org> (raw)
Teach autoprewarm to use the dynamic shared memory registry.
Besides showcasing the DSM registry, this prevents pg_prewarm from
stealing from the main shared memory segment's extra buffer space
when autoprewarm_start_worker() and autoprewarm_dump_now() are used
without loading the module via shared_preload_libraries.
