and, i was able to determine that the problem occurs when i execute 'discard all' query - it is usually being run in our case by pgbouncer:

postgres=# DISCARD ALL;
WARNING: unrecognized node type: 742
DISCARD ALL

on another machine with the same packages - the problem doesn't exist.

what could be the reason behind it?
