Does that include PostGIS datatypes?

That's invalid memory access - like a UNIX segfault (sig11).

Can you show your schema - the definition of the table(s) involved in
the INSERT and any triggers on them? The output of:

\d+ tablename

from psql would do the trick.

Truly, the most helpful thing at this point would be to collect a
backtrace showing where in the postgresql server it crashed. There are
instructions on how to do that here:

http://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Windows

In your case, as the backend is crashing you will want to use windbg or
Visual Studio Express Edition to collect the crash data; process
explorer will not be enough.
