CleanQuerytext() would crash on a NULL string AFAIK, but this really
smells like a case where a utility code path is freeing the pointer of
the query string that PGSS is attempting to look at. I have seen this
problem in the past, where this subtle issue could be created even if
the code was rather careful in the query string handling. Here, are
we dealing with a CALL that involves plpgsql? Or is that a different
language, like something out of core?
