powa-archivist 4.2.0
========

The PoWA team is pleased to announce the release of the version 4.2.0 of powa-archivist, the core extension of the [PoWA project](http://powa.readthedocs.io/), a PostgreSQL Workload Analyzer that gathers performance stats and provides real-time charts and graphs to help monitor and tune your PostgreSQL servers.

- New feature
- Add pg_stat_statements.toplevel field (Marc Cousin, Julien Rouhaud)
- Bugfixes
- Fix a possible long waiting time when the background worker is asleep and another session is waiting for a pending event, like a DROP DATABASE (Julien Rouhaud, thanks for github user anikin-aa for the report)
- Fix pg_stat_kcache support when not all metrics are available (Julien Rouhaud)
- Misc
- Add compatibility with postgres 16 (Julien Rouhaud)
- Immediately exit the bgworker in binary upgrade mode, which could lead to data corruption in the powa database (Julien Rouhaud)
