Are we talking seconds, minutes, hours, days?

If it's not doing recovery then the Postgres time proper should be
no more than a second or so, in my experience.  Look for
outside-the-database factors.  One possibility is a broken DNS
configuration leading to long delays in trying to resolve socket
addresses and such.  I've never seen such a problem causing a delay
over a minute though ....
