pgsql: Revert removal of trace_userlocks, because userlocks aren't gone - Mailing list pgsql-committers

Revert removal of trace_userlocks, because userlocks aren't gone.

This reverts commit 0180bd6180511875db046bf8ddcaa633a2952dfd.
contrib/userlock is gone, but user-level locking still exists,
and is exposed via the pg_advisory* family of functions.
