Seems likely to me that the function is crashing before it gets to any
of the elog calls; which would most likely be a problem in linking or in
declaring the function. Did you remember to use the
PG_FUNCTION_INFO_V1() macro? Try writing a trivial function that only
does an elog and see what it takes to get that to work.
