INSERT INTO drupal users (uid, name, mail, created, access)
SELECT user_id, username, user_email, user_regdate, user_lastvist
FROM phpbb_users where user_id > 50;
This is sort of like an example on
http://www.postgresql.org/docs/9.0/interactive/sql-insert.html, but
that example uses SELCT *. Perhaps an additional example would have
helped? (This is basic SQL, though, and I'm not sure the keyword
manual is the best place for such an example.)
