  1. Suppress unused-variable warning.

  2. Allow partitionwise joins in more cases.

  3. Avoid crash in partitionwise join planning under GEQO.

  4. Disable support for partitionwise joins in problematic cases.

  5. Add plan_cache_mode setting

  6. Add test for partitionwise join involving default partition.

  7. Revise API for partition_rbound_cmp/partition_rbound_datum_cmp.

Fujita-san, amul,

CFbot complains that Fujita-san submitted a patch that doesn't apply,
which makes sense since the necessary previous patch was only referred
to without being resubmitted.  I suggest to always post all patches
together with each resubmission so that it can be checked automatically
by the cf bot: http://commitfest.cputube.org/etsuro-fujita.html

I'm not clear on who the author of this patch is, now.  Also, I'm not
sure what the *status* is.  Are we waiting for Fujita-san to review this
patch?
