Tom Lane b631d01498 Fix pl/tcl's handling of errors from Tcl_ListObjGetElements(). 
In a procedure or function returning tuple, we use that function to
parse the Tcl script's result, which is supposed to be a Tcl list.
If it isn't, you get an error.  Commit 26abb50c4 incautiously
supposed that we could use throw_tcl_error() to report such an error.
That doesn't actually work, because low-level functions like
Tcl_ListObjGetElements() don't fill Tcl's errorInfo variable.
The result is either a null-pointer-dereference crash or emission
of misleading context information describing the previous Tcl error.

Back off to just reporting the interpreter's result string, and
improve throw_tcl_error()'s comment to explain when to use it.

Also, although the similar code in pltcl_trigger_handler() avoided
this mistake, it was using a fairly confusing wording of the
error message.  Improve that while we're here.

Per report from A. Kozhemyakin.  Back-patch to all supported
branches.
