Hi Yesterday I helped a guy on irc with a locking problem, he thought that locking in postgresql was broken. It turned out that he had a PHP function that he called inside his transaction and the function did BEGIN and COMMIT. Since BEGIN inside a transaction is just a warning what happend was that the inner COMMIT ended the transaction and released the locks. The rest of his commands ran with autocommit and no locks and he got broken data into the database.
Could we make BEGIN fail when we already are in a transaction? Looking it up in the sql99 standard I find this: "If a <start transaction statement> statement is executed when an SQL-transaction is currently active, then an exception condition is raised: invalid transaction state - active SQL-transaction." /Dennis ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
