Force client disconnect using PostgreSQL

Question

Is there a way to force clients to disconnect from PostgreSQL? I\'m looking for the equivlent of DB2\'s force application all.

I\'d like to do this on my development

Answer 1

I post my answer because I couldn't use any of them in my script, server 9.3:

psql -U postgres -c "SELECT pid, (SELECT pg_terminate_backend(pid)) as killed from pg_stat_activity WHERE datname = 'my_database_to_alter';"

In the next line, you can do anything yo want with 'my_database_to_alter'. As you can see, yo perform the query from the "postgres" database, which exists almost in every postgresql installation.

Doing by superuser and outside the problem-database itself worked perfect for me.
