Hello Freddy

This could be a solution, but probably not a good/the best one:

1.) Mark out the database in pg_hba.conf, e.g.

# TYPE  DATABASE    USER        IP-ADDRESS        IP-MASK           METHOD
local   T740A       all                                             reject
local   all         all                                             trust

2.) Reload the cluster

pg_ctl reload -D $PG_DATA

or

pg_reload CLUSTER1   # with pg_env

Now no more new connections are possible

3.) Kill all processes which are related to your db

postgres@master:/u00/app/pgsql - rdbms740/template0> ps -fu postgres |
grep T740A
postgres 28375 27864  1 09:16 pts/1    00:00:00 postgres: postgres T740A
[local] idle

ps -fu postgres | grep T740A | grep -v grep | cut -d" " -f2 | \
while read pid ; do
  kill ${pid} 2>/dev/null
done
