Subject: pgsql: Re-introduce pgstat_drop_entry(), keeping ABI compatibility
Date: Mon, 22 Jun 2026 22:59:41 +0000
Message-ID: <E1wbncD-001SXZ-1h@gemulon.postgresql.org> (raw)

Re-introduce pgstat_drop_entry(), keeping ABI compatibility

This routine acts as a wrapper of a new pgstat_drop_entry_ext(), used in
the core code with a missing_ok argument.

This includes an update of .abi-compliance-history, removing the latest
entry that has documented the change of pgstat_drop_entry().  This
change is applied across v15~v18.  HEAD keeps pgstat_drop_entry() as
single entry point, with the new missing_ok.

Per discussion with Álvaro Herrera and Lukas Fittl.  This is a follow-up
of 850b9218c8e4.
