Many thanks Tony and Tom, since this was a "one time" process speed wasn't an issue... I just did a plain pg_dump with insert and explicit column names in the dump, then used vi to rename the columns and get rid of some of them... non very scientific but it worked :) cheers. tgl@sss.pgh.pa.us (Tom Lane) wrote in message news:<14059.1088777527@sss.pgh.pa.us>... > reina_ga@hotmail.com (Tony Reina) writes: > > If the 2 tables have different arrangements, then I'm not sure if > > there is a quick way.
