Thread: pgsql: Add new function log_newpage_buffer.

Add new function log_newpage_buffer.

When I implemented the ginbuildempty() function as part of
implementing unlogged tables, I falsified the note in the header
comment for log_newpage.  Although we could fix that up by changing
the comment, it seems cleaner to add a new function which is
specifically intended to handle this case.  So do that.
