You're running 7.1.2?  My, that *is* an old installation.  You really
ought to think about an update, particularly if you might be approaching
the 4-billion-transaction event horizon.  You do not want to suffer XID
wraparound in a 7.1 installation :-(.  See this link for explanations:
http://www.postgresql.org/docs/7.4/static/maintenance.html#VACUUM-FOR-WRAPAROUND

7.1 does have the CHECKPOINT command, though, whether you see it
documented or not.
