> How would this differ from just UPDATE pg_database SET datallowconn = FALSE for the databases in question?
Several ways actually. First, it is automatically gone when the locking
session disconnects (so it clean ups after itself). Second, it doesn't
require manually updating the catalogs, which is frowned upon (with good
reason). Third, the database owner could do it, not just superuser.
