Re: Alter table never finishes

There are two ways: the first|is based on pg_terminate_backend()
function and 'pg_stat_activity' catalog |||to kill idle processes.
So in a psql session type (tried on PostgreSQL 8.4):

==# SELECT procpid, (SELECT pg_terminate_backend(procid)) AS killed from
pg_stat_activity WHERE current_query LIKE '<IDLE>';

A more heavy handed approach then should be used on terminal, forcing
kill of idle processes using their pid:

:$ for x in `ps -ef | grep -e "postgres.*idle" | awk '{print $2}'`; do
kill -9 $x; done

Hope it can help.
