Re: Problem with default partition pruning

Hello Shawn, Alvaro,

Thank you for testing patches and comments.
Yes, there are two patches:
(1) v4_default_partition_pruning.patch fixes problems with default
partition pruning
and (2) v3_ignore_contradictory_where_clauses_at_partprune_step.patch determines
if a given clause contradicts a sub-partitioned table's partition constraint.
I'll post two patches together next time.

Anyway, I'll rebase two patches to apply on master and fix space.

Regards,
Yuzuko Hosoya
