By that you mean to have a pg_hba.conf file in $PGDATA directory named for
example pg_hba.conf.dump and when
I want to perform the backup/restore to rename it to pg_hba.conf and make a
/etc/init.d/postgresql reload?
and by doing that users will not lose their data between the dump and
restore?
I think by doing /etc/init.d/postgresql reload with the new pg_hba.conf
users will be cut of brutaly, or am I wrong?

Thank you again,

Is there any way to close the connections of other users in PostgreSQL.
I wish to run an automatic pg_dump and pg_restore and I guess users must be
disconnected first.
Is that right?
