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?
