There's code in datumSerialize() that is intended to do the right thing with expanded-object references. But it could have a bug, of course. That function gets called from SerializeParamList(), which might be another place to look for problems if the crash can only be reproduced when there are statement parameters. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
