While we're on the topic of the relation between constraint exclusion and
partition pruning, I'd like to (re-) propose this documentation update
patch.  The partitioning chapter in ddl.sgml says update/delete of
partitioned tables uses constraint exclusion internally to emulate
partition pruning, which is no longer true as of 428b260f8.

The v2-0001 patch hasn't changed.

Thanks,
Amit
