Below is what I listed off as complete when submitting the patch.

'Make constraints clearer in dump file' is questionable.  Foreign keys
are, others not yet, but they need to be.


# Add ALTER TABLE DROP non-CHECK CONSTRAINT
# Allow psql \d to show foreign keys
*  Add pg_depend table for dependency recording; use sysrelid, oid, 
depend_sysrelid, depend_oid, name
# Auto-destroy sequence on DROP of table with SERIAL
# Prevent column dropping if column is used by foreign key
# Automatically drop constraints/functions when object is dropped
# Make constraints clearer in dump file
# Make foreign keys easier to identify
