Subject: pgsql: Add CHECK_FOR_INTERRUPTS in contrib/pg_buffercache functions.
Date: Tue, 19 Aug 2025 19:15:03 +0000
Message-ID: <E1uoRnS-000h5k-3B@gemulon.postgresql.org> (raw)
Add CHECK_FOR_INTERRUPTS in contrib/pg_buffercache functions.
This commit adds CHECK_FOR_INTERRUPTS to loops iterating over shared
buffers in several pg_buffercache functions, allowing them to be
interrupted during long-running operations.
Backpatch to all supported versions. Add CHECK_FOR_INTERRUPTS to the
loop in pg_buffercache_pages() in all supported branches, and to
pg_buffercache_summary() and pg_buffercache_usage_counts() in version
16 and newer.
