[OT?]*_fsm_* parameters in postgresql.conf: which versions supports them?

From
Marco Vezzoli

Hi,
hope this is not too off topic: I run postgresql 7.1.3 on Solaris 8;
I've read on  http://cbbrowne.com/info/postgresql.html that 'You will
only get effective nonblocking VACUUM queries if the dead tuples can be
listed in the Free Space Map': this could be done '[increasing], in
postgresql.conf, the value of max_fsm_pages and max_fsm_relations'.
I didn't found any of these parameter in my postgresql.conf so I suppose
that my version of postgresql is too old.
Which versions supports these parameters?

Yes, your version is too old.

You probably want to upgrade to 7.3.4.
