If this is a one time insert you'll want to remove any indexes and rebuild them after the inserts are done. Also you'll want to look into the COPY command here: http://www.postgresql.org/docs/7.3/static/sql-copy.html Loading the data from file like this is probably going to be much faster than from a script and/or program. --------------------------------- Frank Wiles <frank@wiles.org> http://frank.wiles.org---------------------------------
