You can do CREATE INDEX CONCURRENTLY to build a new index with the same definition, and when that is complete, drop the old index. The locking that is required here is modest: CREATE INDEX CONCURRENTLY needs to lock the table briefly at a couple of points in the operation, and dropping the old index requires a brief lock on the table. It is, however, much less overall lock time than REINDEX would be. -- -- Christophe Pettus xof@xxxxxxxxxxxx
