Just how transient is the memory context created for a C language
function call?
The reason I ask is that I was getting a seg fault when I attempted to
pfree something that should have been palloced. When I commented out the
calls to pfree it worked fine. Most annoying ;-)
I'm still trying to get to the bottom of it, but I want to know if I'm
safe in relying on the context cleanup to handle things for me. It's an
immutable text function returning text, and is intended for use in a
functional index.
