backend debug information

Hello All,

I am working on writing up my "C" extensions but am having a problem with the
backend having a problem and no real useful information is being returned.

I am getting this:
-----------------------------------------------------------------------------

Welcome to psql, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

trdata=# select desdecrypt('a','b');
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!# \q
------------------------------------------------------------------------------

This function is part of a library set that I am using and I know that it works
in regular C++ and have already implemented the encryption side with no
problems.

Is there some place that I can get the debug information when this system
crashes out so that I can look for the problem?

Cheers,
Lonnie
