This may sound like a stupid question, and i apologize if it is, but I couldn't find the answer in any documentation. Every table has a implicit column oid. Does this column have an index on it? I assume not, and I am putting an index on it anyway. The real problem is that I have a table like the following: create table foo ( time timestamp DEFAULT CURRENT_TIMESTAMP, ... ) I insert an row, and I want to get the timestamp of that row. So i do a select on oid. I want an index. Does one already exist? -rchit ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
