The same is true for user-defined C funtions.

The PostGIS GEOS geometry functions come to mind, for complex
geometries, they can need hours to complete. And as GEOS is a 3rd-Party
library, I don't see an easy way to make them CHECK_FOR_INTERRUPTS.

Does anybody know how this is for plpgsql, pljava and plpython?
