Обсуждение: lock a database from new connections, without modifying pg_hba.conf
Is that possible? I've checked the docs for 8.1, and am not finding anything, nor anything in contrib ... the best I've been able to think of so far is to modify pg_hba.conf to not allow new connections for the duration of the operations I need to perform (drop and create a database) ... ---- Marc G.

Not sure I understand what you need. DROP DATABASE already locks out
new connections.

Just in case ... update pg_catalog.pg_database set datallowconn = false where datname = '...'; http://archives.postgresql.org/pgsql-docs/2004-11/msg00015.php http://www.postgresql.org/docs/8.1/interactive/manage-ag-templatedbs.html My twopence.

Can hba be manipulated in such a way to make Postgres "read only" to obtain a complete and full backup please, and if so, how?

PostgreSQL allows "complete and full backups" while in production. E.g; we
support hot backups :). You do not have to stop working just to run backups
(unlike another unnamed database).
