We do not support triggers on system catalogs. The system should have done its best to prevent you from creating one ... I suppose you had to hack around with a "postgres -O" standalone backend? Returning to the original problem, it seems to me that comparing "pg_dump -s" output is a reasonable way to proceed. The problem of inconsistent output format across pg_dump versions is a red herring --- just use a single pg_dump version (the one for your newest server) for all the dumps. Recent pg_dump versions still talk to older servers, back to 7.0 or thereabouts. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
