Missed this at first... I don't think there's any measurable hit now as there is no additional function call as I chose to directly do the work directly in palloc[0]. That causes a minor amount of code duplication but imo thats ok. I didn't do that for pstrdup() but it would be easy enough to do it there as well, but I don't think it matters there. In a quick test I couldn't find any performance difference. I don't think making them STATIC_IF_INLINE functions would help as I think that would still require the CurrentMemoryContext symbol to be visible in the callers context. FWIW I previously measured whether the function call overhead via mcxt.c is measurable and it wasn't...
