Heikki Linnakangas 951b60f7ab Do not emit WAL for unlogged BRIN indexes 
Operations on unlogged relations should not be WAL-logged. The
brin_initialize_empty_new_buffer() function didn't get the memo.

The function is only called when a concurrent update to a brin page
uses up space that we're just about to insert to, which makes it
pretty hard to hit. If you do manage to hit it, a full-page WAL record
is erroneously emitted for the unlogged index. If you then crash,
crash recovery will fail on that record with an error like this:

    FATAL:  could not create file "base/5/32819": File exists
