The pgBadger collection was imported on 2026-08-15 from https://pgbadger.darold.net/ and from darold/pgbadger commit a1ad95a035a0c2d246fe632eb1c361d4bde0ddae.

repository at tag v3.4.3, commit 80ea565fdefbc34ec82d7374d7d19b0107231379. Its English prose is
derived from the complete doc/intro.txt, doc/configuration.txt, and doc/management.txt manuals
