NOTE: This version requires a change to the on-disk format. After
installing the new version restarting PostgreSQL, any previously accumulated
statistics will be reset.
- Add support for architecture that don't provide getrusage(2), such as
windows. Only user time and system time will be available on such
platforms (Julien Rouhaud). - Expose more fields of getrusage(2). Depending on the platform, some of
these fields are not maintained (Julien Rouhaud). - Add a workaround for sampling problems with getrusage(), new parameter
pg_stat_kcache.linux_hz is added. By default, this parameter is discovered
at server startup (Ronan Dunklau). - Add compatibility with PostgreSQL 11 (Thomas Reiss)
- Fix issue when concurrently created entries for the same user, db and
queryid could lost some execution counters (Mael Rimbault) - Do not install docs anymore (Ronan Dunklau)
