1.4 --- - Provide PostgreSQL 13 support: - add `backend_type` column to `sqlog.log()` output; - add WAL usage data to `sqlog.autovacuum()` output. - Make the functions' security _definer_, thus allowing roles with lower privileges to use the extension (when granted access to the _sqlog_ schema). - Add `sqlog.summary()` function, allowing to strip meta data from the query and dispaying just the first N, the last N, or both characters of it. 1.3 --- - Allow querying of slave node logs. - Optimise `sqlog.autoanalyze()` and `sqlog.autovacuum()` routines. 1.2 --- - Fix `sqlog.preparable_query()` regular expression incorrect handling of numbers within database identifiers. - Make `sqlog.autovacuum()` support older PostgreSQL versions all the way down to 9.3. 1.1 --- - Fix `sqlog.preparable_query()` regular expression incorrect handling of timestamps and exotic data types within an IN list. 1.0 --- - Initial version.
