Hi, Our application requires a number of processes to select and update rows from a very small (<10 rows) Postgres table on a regular and frequent basis. These processes often run for weeks at a time, but over the space of a few days we find that updates start getting painfully slow. We are running a full vacuum/analyze and reindex on the table every day, but the updates keep getting slower and slower until the processes are restarted. Restarting the processes isn't really a viable option in our 24/7 production environment, so we're trying to figure out what's causing the slow updates.

The environment is as follows: Red Hat 9, kernel 2.4.20-8 PostgreSQL 7.3.2 ecpg 2.10.0 The processes are all compiled C programs accessing the database using ECPG. Does anyone have any thoughts on what might be happening here?
