Ah.., no we're not vacuuming template0 or 1.
I didn't realise that the transaction ID would be stored here - I
assumed that they'd be in our database.
Do I need to need to (plain) vacuum, or vacuum full these template0 and
template1? And is this something that can be done once a week rather
than every night (like our main database)?
Thanks for your help.
