Mmm, I'm not sure.  The known variant of this problem only affects certain
system tables (the nailed-in-cache ones):
http://archives.postgresql.org/pgsql-hackers/2002-11/msg00486.php

This is evidently a user table:

> WARNING:  Rel site_search: Uninitialized page 1 - fixing

I'd wonder about hardware failures, myself.  Does the table appear
to have lost a lot of rows that should have been there?

Other interesting questions are whether the table has recently undergone
a TRUNCATE, or deletion of a large fraction of its rows followed by
VACUUM (probably VACUUM FULL).
