Minor patch to correct erroneous warning in cvs tip, believed to be a
very minor regression.
When a shutdown was requested within CHECKPOINT_SECONDS of a checkpoint,
the shutdown code in the bgwriter (which has does checkpointing) would
issue the erroneous message:
LOG: checkpoints are occurring too frequently (%d seconds apart)
HINT: Consider increasing the configuration parameter
Clearly, this should only occur when specific checkpoint requests have
been made, shutdown checkpoints should not be included in the warning.
