If a temporary table with an identity column and ON COMMIT DROP is created in a single-statement transaction (not useful, but allowed), it would leave the catalog corrupted. We need to add a CommandCounterIncrement() so that PreCommit_on_commit_actions() sees the created dependency between table and sequence and can clean it up. The analogous and more useful case of doing this in a transaction block already runs some CommandCounterIncrement() before it gets to the on-commit cleanup, so it wasn't a problem in practical use. Several locations for placing the new CommandCounterIncrement() call were discussed. This patch places it at the end of standard_ProcessUtility(). That would also help if other commands were to create catalog entries that some on-commit action would like to see.
