class QueryFactory

PostgreSQL specific entity query implementation.

To add a new query implementation extending the default SQL one, add a service definition like pgsql.entity.query.sql and a factory class like this. The system will automatically find the relevant Query, QueryAggregate, Condition, ConditionAggregate, Tables classes in this namespace, in the namespace of the parent class and so on. So after creating an empty query factory class like this, it is possible to just drop in a class extending the base class in this namespace and it will be used automatically but it is optional: if a class is not extended the relevant default is used.
