It could be if the type is not marked toastable (ie, has storage class
PLAIN, which I think is the default even for varlena types).
But in any case I suspect that 90% of the problem here is an incorrect
declaration of the *function* not the type. We haven't seen the C
function declaration, nor the SQL CREATE FUNCTION command, but if it's
going through fmgr_oldstyle then there isn't a PG_FUNCTION_INFO_V1
marker, which maybe is the problem.
