Three routines in pgstat_database.c incorrectly ignore the database OID provided by their caller, using MyDatabaseId instead: - pgstat_report_connect() - pgstat_report_disconnect() - pgstat_reset_database_timestamp() The first two functions, for connection and disconnection, each have a single caller that already passes MyDatabaseId. This was harmless, still incorrect. The timestamp reset function also has a single caller, but in this case the issue has a real impact: it fails to reset the timestamp for the shared-database entry (datid=0) when operating on shared objects. This situation can occur, for example, when resetting counters for shared relations via pg_stat_reset_single_table_counters(). There is currently one test in the tree that checks the reset of a shared relation, for pg_shdescription, we rely on it to check what is stored in pg_stat_database. As stats_reset may be NULL, two resets are done to provide a baseline for comparison.
