Tomas Vondra e8b6ae2130 Fix handling of opclauses in extended statistics ... We expect opclauses to have exactly one Var and one Const, but the code was checking the Const by calling is_pseudo_constant_clause() which is incorrect - we need a proper constant. Fixed by using plain IsA(x,Const) to check type of the node. We need to do these checks in two places, so move it into a separate function that can be called in both places. Reported by Andreas Seltenreich, based on crash reported by sqlsmith. Backpatch to v12, where this code was introduced.
