Commit131f801

Browse files
committed
First phase of applying Rod Taylor's pg_depend patch. This just adds
RESTRICT/CASCADE syntax to the DROP commands that need it, and propagatesthe behavioral option through the parser to the routines that executedrops. Doesn't do anything useful yet, but I figured I'd commit thesechanges so I could get out of the parser area while working on the rest.
