Re: about memory size reported by system.

Are you using any connection pooling system, if not look at the pgpool & pgbouncer.

open connections always reserves memory, which slowdown the performance of system.

you can also handle application connections at application level by defining garbage
value if any connection disconnect. It will release the memory reserved by connection.

Subject: [GENERAL] about memory size reported by system.

Hi everyone!

I have a doubt about the memory consumed by each connection open.

suddenly my server, running postgres 8.3.11, began to run too slowly.

Checking the process with: ps -adelfo pcpu,vsz,args | more

The processes,related to the connection to the db, each one have a consume of memory near to the 50Mb. by the way i have 50 connections to the db, so i have a reported memory consumed of 2.5M, when i have only 1G in the server.

If I modify the shared_buffers value, the report of memory consumed is according with shared buffers value.

Should I worry by that?
There is a best way to tweak the memory consumed by postgres?
