Kaigai-san,

The v3 patch had conflict in src/backend/tcop/utility.c for newly
added IMPORT FOREIGN SCHEMA statement, but it was trivial.

ISTM that doc/src/sgml/custom-plan.sgml should be also renamed to
custom-plan-provider.sgml.

A "custclass" remains in a comment in
src/include/catalog/pg_custom_plan_provider.h.

Check.  I found some typos and a wording "datatype" which is not used
in any other place. Please refer the attached patch.
