yeah, there's a good example in the docs here:
http://www.postgresql.org/docs/9.1/static/contrib-dblink-connect.html
btw, if you have a structure in test that matches production, then you
can use a composite type trick to avoid having to specify fields as
long as you keep those structures in sync (which you have to do
anyways). try:
select (u).* from dblink(
'hostaddr=123.123.123.123 dbname=ProductionDB user=ROUser
password=secret',
'select u from users u') as t1(u users);
it should work as long as users exists on both sides and has exactly
the same structure. using that method it's trivial to make a dblink
wrapper that could query any table but you couldn't wrap it into a
single view obviously.
