If the client application (or pooler) doesn't close the database connections gracefully, it might take some time before the server figures out the connection is dead and frees the resources on the server side. Does the server log say anything about broken connections or client not responding? Also, the pooler might maintanin some *minimum* number of connections but go beyond that "on demand". Without knowing what pooler and how it is configured, it's hard to say what might be going on. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
