They will affect timing for those who are trying to tune queries, and may well affect other behaviours. Not to mention the fact that the user might be running a complex script that we would have to parse client-side to try to figure out where to add the limit/offset (and likely get it wrong). > Monitoring memory usage or PG_stat_activity shows that all the data is > fetched. Sure - pg_stat_activity (it's all lower case) will show the connection state as idle. But the point is - until it does, the query is still being processed and we don't get the data. -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company
