You need to keep in mind that those are per-operation settings, so for example if you have 100 clients performing queries, this could grow up to 100G. In your case you even have a maximum of 900 connections... Do you perform heavy sort operations with your application that could explain such an amount of memory needed? -- Michael -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
