Okay. So I'm right in thinking that
-> VACUUM then CLUSTER VACUUM pointless
-> VACUUM ANALYZE then CLUSTER ditto
-> CLUSTER then VACUUM ditto
-> CLUSTER then VACUUM ANALYZE ANALYZE useful

Sure. Is the HTML the documentation source format as well, or is there
some SGML or something else that I should create patches against?
BTW, you mentioned PostgreSQL 7.2. I assume you were just pointing out
that you can ANALYZE independently of a VACUUM in 7.2, rather than
recommending its use in a hard-working production environment?
Last thing... any chance that CLUSTER will learn some time soon to
automatically recreate my indeces and grants for me? :-)
Thanks!
