It is not possible in the 2.9 series to have TXT records (or content)
longer than 255 characters. You can always create multiple TXT records
for the same name. If you to an alter table, add the larger txt record
and request it, you'll get a broken packet.

Also, please consider upgrading to PowerDNS 3.X as the 2.9 series is
absolutely end of life [1].
