There are 98K records in the table. There is no index on the make_id field. Standard untouched postgresql.conf from the brew install of postgres. > Unlikely.

As mentioned above the setup is really simple. Standard postgres install, the default conf file, update one field on one table. It takes fifty plus seconds. I concede that if I was to go into the postgres.conf and make some changes it will probably run faster (maybe much faster) but I wanted to exhaust other factors before I went messing with the default install. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
