The bloat seems to be here:

but it's hard to believe you'd be getting "out of memory" after only
130MB in a 64-bit build.  Are you *sure* the postgres executable is
64-bit?  Are you *sure* the postmaster has been launched with
nonrestrictive ulimit?  On lots of setups that takes modifying the
PG startup script, not just fooling with some user's .profile.
