Have you considered building with LWLOCK_STATS defined, and LOCK_DEBUG defined? That might do it. Otherwise, I suggest dereferencing the "l" argument to LWLockAcquireWithVar() or something -- set the frame to "3" in your example backtrace, using "f 3". Then, "p *l". You'll get the tranche id there, and so on. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
