Re: Vacuum template databases, Urgent: Production probl

Humm, well I am running 8.0.1 and use that option and see the following in my vacuum output log:

vacuumdb: vacuuming database "template1"

So I would assume that it is being vacuumed?  Maybe I'm wrong.  If so, we should be upgrading soon and it won't be an issue.

Thanks,
Tim

It does on 8.1...

decibel@phonebook.1[15:15]~:18%vacuumdb -va | & grep template1
vacuumdb: vacuuming database "template1"
decibel@phonebook.1[15:16]~:19%

Try it and find out.

My guess is that vacuumdb -a will vacuum anything that it's allowed to
connect to, which normally means every database except for template0. If
you want the Real Answer, look in the source.

it has done so since at least 7.4, probably 7.3.  the "-a" flag
really does what is says.
