I'd expect this would take something more like 10 minutes.  Things to
check, are you recovering in the same instance?  Another machine?  I've
noticed some funkyness when the table exists, but is emptied.  I'd drop the
tables and recreate.  Also, it often goes much faster is you load without
indexes, and create them later.  You might also want to adjust your shared
memory parameters up some, but you have to restart the postmaster for it to
take effect.

There is definitely something wrong, because i've seen recovery to be
pretty darn fast.
