The steady-state situation should be that you have max_connections of them, more or less, if you ever get up to max_connections live connections. > On a side note: I can drop temporary tables of other sessions via "DROP > pg_temp_xx.table" (although I can't seem to affect table data seen from > other session). Is there any security issues/gotchas here? If you can do that without being superuser, I'd take an interest. Otherwise the answer is "don't do that". regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
