In addition to the added functions, the pg_buffercache_evict() function now shows whether the buffer was flushed. pg_buffercache_evict_relation(): Evicts all shared buffers in a relation at once. pg_buffercache_evict_all(): Evicts all shared buffers at once. Both functions provide mechanism to evict multiple shared buffers at once. They are designed to address the inefficiency of repeatedly calling pg_buffercache_evict() for each individual buffer, which can be time-consuming when dealing with large shared buffer pools. (e.g., ~477ms vs. ~2576ms for 16GB of fully populated shared buffers). These functions are intended for developer testing and debugging purposes and are available to superusers only. Minimal tests for the new functions are included. Also, there was no test for pg_buffercache_evict(), test for this added too. No new extension version is needed, as it was already increased this release by ba2a3c2302f.
