Re: autovacuum ignore tables

I meant to say...rules are used on the parent table to redirect to
child. Just like the way the postgres 8.1 documentation has it.

A check constraint can't redirect anything.  Are you saying that you use
a trigger to try to insert the row into *each* child table, relying on
the constraints to make all except one insert fail?  Ugh.  You'd do a
lot better to duplicate the partitioning-rule knowledge in the trigger,
and do only one insert that should succeed --- no wasted cycles, and no
need for a subtransaction.
