I think /etc/security/limits.conf is used to limit what you can set with
ulimit rather than dictate the settings. You probably need to put
"ulimit -c unlimited" in ~postgres/.bash_profile.

The core file produced by postmaster from the binary package will not be
very useful to you, because the binary is stripped. You need to build
the package from source and use the binary from the source tree
(.../src/backend/postmaster/postmaster), not the one copied into the
package tree (.../debian/usr/lib/postgresql/bin/postmaster) since the
stripping is done on the package tree after the binaries are installed
To build the package:
apt-get source postgresql # installs in postgresql-7.2.2
apt-get build-dep postgresql # build dependencies
apt-get install devscripts fakeroot # needed for building anything
