indeed something i could use as reference i'm actually looking for a way to compare two sql statement, and to check if they are equivalent (not only semantically, since this usually makes a difference in execution plan). i suppose the postgresql internal must have some sort of functions handling this, while parsing the statement. i would be handy to have this function available as a db user. tnx, Wim > > regards, tom lane > -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
