That extension is broken on its face. You cannot have an emit_log_hook
that does catalog access, because elog() can be called outside a
transaction or in an already-failed transaction. Whatever band-aids
you put around that will just be band-aids that will fail regularly.
You need to move the catalog lookup someplace else. (Actually, I wonder
why you're doing a catalog lookup at all ... wouldn't it be sufficient to
do a DirectFunctionCall to inet_out?)
I doubt this has much to do with the OP's issue.
