Thread: pgsql: Fix documentation reference to maximum allowed for autovacuum_fr

Fix documentation reference to maximum allowed for autovacuum_freeze_max_age.

The documentation mentioned setting autovacuum_freeze_max_age to
"its maximum allowed value of a little less than two billion".
This led to a post asking about the exact maximum allowed value,
which is precisely two billion, not "a little less".

Based on question by Radovan Jablonovsky.  Backpatch to 8.3.
