In Postgres 7.1, ${PGDATA}/base contains directories named by numbers!! They used to be database names. If a user created a db, can the db admin know what is that db name (without sending any query to db server)? I believe there must have some kind of mapping table exist. Can anyone tell me where to find it? Thanx for your help LM.Liu ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
