Use a HASH table before implementing this in SQL.
/etc/postfix/main.cf:
transport_maps =
hash:/etc/postfix/transport ..whatever you already have...
/etc/postfix/transport:
u...@test.com smtp:[the old machine]
# postmap hash:/etc/postfix/transport
# postfix reload
# postmap -q u...@test.com hash:/etc/postfix/transport
smtp:[the old machine]
Once you have that working, start playing with SQL.
