Expand the output parameters in pg_walinspect's pg_get_wal_block_info function to return additional information that was previously only available from pg_walinspect's pg_get_wal_records_info function. Some of the details are attributed to individual block references, rather than aggregated into whole-record values, since the function returns one row per block reference per WAL record (unlike pg_get_wal_records_info, which always returns one row per WAL record). This structure is much easier to work with when writing queries that track how individual blocks changed over time, or when attributing costs to individual blocks (not WAL records) is useful. This is the second time that pg_get_wal_block_info has been enhanced in recent weeks. Commit |
