Thread: close database, nomount state

Hello,
I want to ask if there is something like nomount state or close database state
in which I can acces postgresql to drop database or to do some other stuff.

Because when there are some connections, drop database is not
possible. Or is this done some other way?

change the permissions on the DB so nobody can log in.  you really
should find all applications that are trying to login and shut them
down, else they'll start spewing errors once you delete the DB.

Short answer-- no.

Longer answer-- there's really no need for the Oracle-esque nomount
state in Pg. If you're doing media recovery, it's very much all or
nothing, cluster-wide. You are not going to do media recovery for a set
of tablespaces, for example. If you'd like to drop a database, you can
cut off connections (say, via pg_hba.conf or whatever floats your boat)
and drop it with a single command. It's not such a big deal as it is in
Oracle.

If this doesn't answer your question, could you say more about what your
issue is?

Thanks for your response,
that was exactly what I wanted to know. I was thinking about
pg_hba.conf but I was hoping there is some more elegant way
to do that :-)
