pg_stat_statements: Add counters for generic and custom plans This patch adds two new counters to pg_stat_statements: - generic_plan_calls - custom_plan_calls
These counters track how many times a prepared statement was executed using a generic or custom plan, respectively, providing a global equivalent at query level, for top and non-top levels, of pg_prepared_statements whose data is restricted to a single session. This commit builds upon e125e360020a. The module is bumped to version 1.13. PGSS_FILE_HEADER is bumped as well, something that the latest patches touching the on-disk format of the PGSS file did not actually bother with since 2022..
