This isn't going to fix the problem --- all the functions are still
declared to take type NAME, which will not be long enough for qualified
names. You need to replace the use of NAME with use of TEXT.

I don't particularly care for that answer. Would instead suggest you
borrow the coding now being used in sequence.c and other places where
text arguments are interpreted as relation names:
text *seqin = PG_GETARG_TEXT_P(0);
RangeVar *sequence;
Oid relid;
sequence = makeRangeVarFromNameList(textToQualifiedNameList(seqin,
"nextval"));
relid = RangeVarGetRelid(sequence, false);
// or better, do heap_openrv directly
