Thanks to Erik, Jeff, & Richard for their help. I have a further inheritance question: do child tables inherit the indexes created on parent columns, or do they need to be specified separately for each child table? I.e., created via CREATE INDEX. I assume at least that the implicit index created by a primary key would inherit, but I don't know if that assumption is safe. Thanks, Keary Suska Esoteritech, Inc.
