It saves 4 bytes per row; depending on alignment and padding
considerations, that may or may not equate to disk space savings. Other
than the inability to use OIDs on the table, there is no real risks to
doing this -- I'm planning to advocate making WITHOUT OIDS the default
in PostgreSQL 8.1+. You can get this behavior in 8.0 by setting the
default_with_oids config variable to "false".
