• minor_version: check if the PostgreSQL minor version is the latest one.
• oldest_2pc: check the oldest two-phase commit transaction.
• oldest_idlexact: check the oldest idle transaction.
• oldest_xmin: check the xmin horizon from distinct sources of xmin retention.
• pg_dump_backup: check pg_dump backups age and retention policy.
• pga_version: check the version of this check_pgactivity script.
• pgdata_permission: check that the permission on PGDATA is 700.
• replication_slots: check delta in bytes of the replication slots.
• sequences_exhausted: check that auto-incremented colums aren't reaching their upper limit.
• settings: check if the configuration file changed.
• stat_snapshot_age: check stats collector's stats age.
• streaming_delta: check delta in bytes between a master and its standbys in streaming replication.
• table_bloat: check tables bloat.
