@MironAtHome It appears that if the PG type Name is used, then it will
always be truncated at `NAMEDATALEN` on input -
```
Datum
namein(PG_FUNCTION_ARGS)
{
char *s = PG_GETARG_CSTRING(0);
Name result;
int len;
len = strlen(s);
/* Truncate oversize input */
if (len >= NAMEDATALEN)
len = pg_mbcliplen(s, len, NAMEDATALEN - 1);
/* We use palloc0 here to ensure result is zero-padded */
result = (Name) palloc0(NAMEDATALEN);
memcpy(NameStr(*result), s, len);
PG_RETURN_NAME(result);
}
```
This also means that there won't be any warning if it exceeds `NAMEDATALEN`
:(
