Yes, you are right. I was going to say that we are not very consistent 
on when to use ereport() and when PLy_elog() in general, but looking 
closer, we are. Outside the array-conversion functions, PLy_elog() is 
only used when a Python C API call fails, and ereport() is used otherwise.

Patch attached.
