After receiving a notification from libpq (PQnotifies), each client proceeds to execute a query for the last five records in the timeclock table.
SELECT * FROM timeclock ORDER BY touched DESC LIMIT 5;
It varies, but it's often the case that clients wait up to 3 minutes before the results come back. This seems like a really long time for a query that I would think would go quickly. In fact, I can execute the same query from a third party client and it runs fine, even while my own client is still waiting for results.
Any ideas? It seems to be related to NOTIFY/LISTEN. Thanks!
