Unimpletmented features

From the ALTER TABLE documentation on postgresql.org

Synopsis

ALTER TABLE [ ONLY ]table [ * ]
    ADD [ COLUMN ] column type
ALTER TABLE [ ONLY ]table [ * ]
    ALTER [ COLUMN ] column { SET DEFAULT value | DROP DEFAULT }
ALTER TABLE table [ * ]
    RENAME [ COLUMN ] column TO newcolumn
ALTER TABLE table
    RENAME TO newtable
ALTER TABLE table
    ADD table constraint definition

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

What happened when I tryed it:

DBD::Pg::db do failed: ERROR:  ALTER TABLE / ADD CONSTRAINT is not implemented

If I find another unimplemented 'feature' of postgresql 7.0.2 documented
in the manual I swear to god I'm going to go postal.

How about a 'not yet implemented in 7.0' line in the documentation for
this stuff?
