An extension *has* an OID, doesn't it? pg_extension has 'em. If the extension script could somehow be informed at CREATE EXTENSION time of what its OID is, that would clear the way for ALTER EXTENSION RENAME, no? Somehow, I find this first idea more aesthetically appealing than actually trying to bind things in extensions to fixed OIDs for all time. -Chap
