Subject: [PATCH 4/4] Additional test for new GUC setting.
Date: Wed, 28 Aug 2019 14:12:18 +0900
This patchset adds new GUC variable effective_io_block_size that
controls wheter WAL-skipped tables are finally WAL-logged or
fcync'ed. All of the TAP test performs WAL-logging so this adds an
item that performs file sync.
