But you lose all your RI constraints. I keep the RI constraints in a separate file so I can re-create them when I need to ...

There isn't a DROP COLUMN function yet, but you can do this...
SELECT ... -- select all columns but the one you want to remove
INTO TABLE new_table
FROM old_table;
DROP TABLE old_table;
ALTER TABLE new_table RENAME TO old_table;
This is straight out of Bruce Momjian's book, so you can give him credit for
this :)

I know this is an easy question, but I can't find any info on how do
this in the PostgreSQL book. How do you delete a column? I've been
able to delete tables, db's, rows, etc. But can't figure out how to
just delete a column. I'm running RedHat 7.2 and PostgreSQL 7.1
Thanks for any help.
