I created the following record via the API:

{
   "comments": [],
   "name": "%s" % zone,
   "records": [{ "content": "ibm.com.", "disabled":False }],
   "ttl": 120,
   "type": "ALIAS"
},

The record correctly shows up in sqlite3:

sqlite> select * from records where domain_id = (select id from domains where name = 'blurb.com');
137|16|blurb.com|TXT|"ceci n'est pas une pipe"|120|0||0||1
138|16|blurb.com|ALIAS|ibm.com|120|0||0||1
139|16|blurb.com|NS|pdns.int|3600|0||0||1
140|16|blurb.com|SOA|pdns.pdns.int hostmaster.blurb.com 2 10800 3600 604800 3600|3600|0||0||1
141|16|www.blurb.com|A|1.1.1.1|60|0||0||1
142|16|blurb.com|A|127.0.0.1|60|0||0||1

PowerDNS is configured to not expand aliases.

The ALIAS's value is incorrect: it has a compressed label in it.

18:51 < ahu> so this is 3IBM and then a label pointer
18:51 < ahu> no this should not ever be in a record
18:51 < ahu> and it should not be compressed
18:51 < jpmens> that's what I thought
