An array containing the primary key for the associated model.

193:         def associated_object_keys
194:           Array(primary_key)
195:         end

pg_array_to_many associations can only have associated objects if the array field is not nil or empty.

199:         def can_have_associated_objects?(obj)
200:           v = obj.get_column_value(self[:key])
201:           v && !v.empty?
202:         end

pg_array_to_many associations do not need a primary key.

     # File lib/sequel/plugins/pg_array_associations.rb, line 205
205:         def dataset_need_primary_key?
206:           false
207:         end

Use a default key name of *_ids, for similarity to other association types that use *_id for single keys.

211:         def default_key
212: 
213:           "#{singularize(self[:name])}_ids"
214:         end

Always use the ruby eager_graph limit strategy if association is limited.

246:         end
