ODBC & Postgres problem

I am new to this mailing-list and I have a problem with (Insight)ODBC & PostgreSQL.
I have searched the pgsql-interfaces archive to solve my problem but that did not
help me much.

I have installed - following the steps in the INSTALL readme -
postgresql 6.3.2 on my linux (glibc) server

I am trying to access a database I created with InsightDist ODBC and Visual
Basic 5.0 RDO and I have two problems.

First of all postgres uses alot of memory and is really slow, while an ODBC
connection is active:

[postgres(at)downtown /root]$ ps aux | grep postgres
postgres 19740 0.0 0.5 1420 252 p0 S 20:56 0:00 su postgres
postgres 19741 0.0 1.2 1172 580 p0 S 20:56 0:00 bash
postgres 19746 0.0 0.6 5060 284 p0 S 20:57 0:00 postmaster -i -B 256
postgres 19749 13.2 82.5 56664 38704 p0 S 20:58 0:16 /usr/local/pgsql/bin/postgres -p -Q -P5 -B 256 -v 65536 foo
postgres 19753 0.0 1.0 832 504 p0 R 21:00 0:00 ps aux
postgres 19754 0.0 1.2 1172 580 p0 R 21:00 0:00 bash
[postgres(at)downtown /root]$

I have 48MB Ram and a big swap, but it uses far too much memory.

The second problem I run into is that when I use RDO or RDC/RDO I cannot activate the
"UseCursor" Option for the ODBC driver and I everytime I try to insert,update or
delete a record I am told that the resultset is writeprotected (Error number 40048)

Can anybody help me one these problems.
