Anyarray also provides a calculation of similarity two one dimensinal arrays similar to smlar module. Anyarray module doesn't provide an something similar to query_int feature of intarray, because this feature is very hard to implement (it requires new pseudo-type anyquery), it is close to impossible to have operation extensibility and it's complicated queries are hidden from pgsql's optimizer (like to jsquery). As far I know, query_int isn't very popular for now.
