What cases have you gotten to work correctly?

My guess is that you're either messed up about V0 vs V1 calling
convention (ie you forgot PG_FUNCTION_INFO_V1, or added it when you
shouldn't have), or you've got some kind of problem with not detoasting
toasted input values.  There's not enough info here to venture more.
