I am using postgresql 9.2, and we are getting error like - System.Data.EntityException: The underlying provider failed on Open. ---> Devart.Data.PostgreSql.PgSqlException: Stream already closed!!!. I have turned the autovacuum on but my reporting query is failing. When the manual full autovacuum is performed along with analyse the reporting query works. Please let me know how to deal with this situation.
