Hi!
I have the next messege:
LOG: checkpoints are occurring too frequently (-21093 seconds apart)

Postgres 8.3.11 is running on SCO Openserver 5.0.7

and this is my   checkpoint configuration:
# - Checkpoints -

checkpoint_segments = 32        # in logfile segments, min 1, 16MB each
checkpoint_timeout = 15min        # range 30s-1h
checkpoint_completion_target = 0.7    # checkpoint target duration, 0.0
- 1.0
#checkpoint_warning = 30s        # 0 is off


Any idea, why i get negative value????
