from having to do writes. On such systems

one should increase the number of <acronym>WAL</acronym> buffers by

modifying the configuration parameter <xref

linkend="guc-wal-buffers">. The default number of <acronym>WAL</acronym>

buffers is 8. Increasing this value will

correspondingly increase shared memory usage. When

linkend="guc-wal-buffers">. When

<xref linkend="guc-full-page-writes"> is set and the system is very busy,

setting this value higher will help smooth response times during the

period immediately following each checkpoint.
