Is there a view or command that can provide this information. The pg_stat_database shows the current number of connections, but not the high-water mark a database had reached. It's a pretty easy thing to approximate with a shell script. while true;do ps ax|grep postgres:|grep -v grep|wc -l ;sleep 10;done > connects.log & then just tail the connects.log file. It's a dirty hack and it'll be a few counts over due to counting the postmaster and a few other processes, but it'll give you a good idea of what your system is doing. Add a date in there if you need to know the time it was happening. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
