Thread: Re: [ADMIN] slower every day

Again me,

   To make it easier.

Situation A:
log_something = true

Situation B:
# log_something = <anything>

Situation C:
log_something = false

After the pg_ctl reload:

Situation B = Situation A
Situation C <> (Situation A || Situation B)

Is this the expected behavior?

Conclusion:

If you comment a line on the conf file, and reload it, will remain in the last state. (either wast true or false, while
Iexpected a default) 

Regards

realizethat this is MY MISTAKE, the log defaults on a reload, if commented, tend to be the last value entered?

Yes, that's correct. No, you're not the only one to have been caught out
by this.
