Hi,
Thanks for the answer ...
But honestly I think that was a misunderstood.
The memory increase issue is showed in the DATA column.
Look how day by day it increases exponencially.
In a few days PostGres goes out of memory, close the connections and enter in a recovery mode.
I really don’t know what is causing it.

shared memory, which puts both of those backends at using an
individual amount of memory at somewhere in the 5 to 8 meg range. The
rest is shared memory, including shared_buffers and such.
Seeing as you say your shared_buffers is 512M, I'm not sure where the
rest of the shared memory is coming from here in top.Note that your machine is still showing 3.6G or so used for caching

our of 4G, so you're only using an actual amount of about 400 Meg
Are you having any measurable performance issues, or just curious /
worried about what seems like high memory usage? Your numbers look
pretty normal to me otherwise.
