Subject: pgsql: Retire execdebug.h and its debugging facility
Date: Sat, 22 Aug 2026 07:23:43 +0000
Message-ID: <E1wxg4s-00000001cT0-2Afc@gemulon.postgresql.org> (raw)
Retire execdebug.h and its debugging facility
execdebug.h includes "pretty old and crufty" code used to print
debugging information in the executor. As reported recently, this code
has not compiled in the last 10 years or so, and there are better
alternatives available, such as elog().
There is no indication that this facility is still being used, so remove
it along with its associated debugging macros:
EXEC_NESTLOOPDEBUG
EXEC_SORTDEBUG
EXEC_MERGEJOINDEBUG
