Yes, the trigger is written in C. But I didn't find any way to get 
access to the current EState or QueryDesc from a trigger function. The 
only common place of a trigger and the corresponding EState/QueryDesc 
structs seems to be CurrentMemoryContext in a trigger function, which 
ancestor has to be (?) EState->es_query_cxt. It's an ugly solution of 
course.

P.S. Is it a mistype EState->es_query_cxt? Should it be es_query_ctx?
