Обсуждение: After adjusting checkpoint related entries in postgresql.conf...

Hi everybody,

After adjusting checkpoint related entries in postgresql.conf
file, is it sufficient to issue:
  pg_ctl reload
Or am I supposed to do more than that?

Thank you in advance.

Hi Farhan,

> Are you facing any problems?

Yes, the files in data/pg_xlog directory hasn't been
updated.  Here's the setting as far as checkpint
entries are concerned:

  checkpoint_segments = 3
  checkpoint_timeout = 5min
  checkpoint_warning = 30s

Does checkpoint not happen if there is no activity?
The last entry I see in the serverlog file is:

  2007-08-20 16:47:51.152 PDT] <  >LOG:  received SIGHUP, reloading configuration files

Thank you.

Tena

A reload should be enough. Are you facing any problems?
