I have a database table that has about 90k entries, they are all straightfoward text, and there is only one ID field that I use as primary key for this table. I have two threads working on this table. One of them inserting new content constantly, (about every second) another one idles and only wakes up when I want to query(select) the table. My problem is that from the log it seems to me that since the insertion is done far frequently than query, the query thread never finishes its job. It just hangs there for a long time until I kill it by restarting postgresql. (Even statements like EXPLAIN ANALYZE will hang) My question is : Is my suspicion correct? And would upgrading to 8.0 (or any later 8.x version of postgresql) help with my specific demand? I am using PostgreSQL 7.4.13. Thanks Wei
