In PostgreSQL 8.4.9 with pgbouncer 1.3.4 in pool_mode = session (but some users connect to the database directly) - when I login as "super user" with
psql -U postgres -W postgres
What is the command please to disconnect all "normal users" and prevent them from connecting again while I perform maintenance (I'd like to rename some table columns for more consistent naming and correspondingly change some stored procedures).
I can't find it in the III. Server Administration doc.
Or should I edit pg_hba.conf and restart the service/process?
