Обсуждение: freeing disk space used by postgresql/postmaster

Hi
We are experiencing this scenario -
1. at the point postgresql (postmaster) is stopped and restarted the disk
usage was 56% (277336 blocks)
2. after about 2 days the disk usage is 69% (339528 blocks)... after about
1 week it goes up to 100%
3. after stopping and restarting postgresql (postmaster) again the disk
usage is back to 56%
Do we need to start and stop postgresql regularly to free up disk space -
is this normal?
I vacuum the databases regularly but this does not seem to make any difference.
Many Thanks,
Colleen.

Oh?  Stopping and restarting the postmaster shouldn't make any
difference as far as postgres itself is concerned.  May I ask what
you are doing with the postmaster log (stdout & stderr)?  How high
do you have the debug level set?
