Обсуждение: Why "vacuum_freeze_min_age" parameter has context as "USER" ?

Hi,

     Can you please tell me what is the purpose of providing  * USER*
context to *vacuum_freeze_min_age* parameter.
I guess vacuum process only going to use it.  so if i changed
*vacuum_freeze_min_age* and issue VACCUM command on a session. Will postgres
VACCUM process takes the changes i made on the session? ...
Is any way to ensure that vacuum command takes  vacuum_freeze_min_age from
session...

Thanks in advance ...
Regards,
Sudalai.

Yes, if you change it within a session and then run a VACUUM
command within that same session, the behavior of VACUUM will be
based on the session setting.
