I'veattached my code below. I am writing this for a Code Interface Node in LabVIEW. 

One thing you're missing is that you should check that the result from
the PQexec actually shows successful entry into COPY_OUT state.
But I think the crash is because you're confused about the indirection
level.  buffer should be char *, not char **, and the argument ought to
be &buffer so that the function can assign to buffer.
