Added GUC variable bgwriter_flush_method controlling the action
done by the background writer between writing dirty blocks and

none (default) no action
sync bgwriter calls smgrsync() causing a sync(2)
A global sync() is only good on dedicated database servers, so
more flush methods should be added in the future.
