Description
The ORMQueryBuilderLoader tries to guess the identifier type to perform filter out invalid values for integral or UUID types by matching a hardcoded list of Doctrine type names. However there are cases that guessing is not working properly and it causes invalid queries to be constructed.

In my case I have separate UUID types for each entity, such that I have strong typing in PHP for these IDs. Lets say BlogId (doctrine name blog_id) and PostId (doctrine name post_id).

When using an EntityType, internally constructing a ORMQueryBuilderLoader, it fails to filter out empty strings. This creates a query Postgres chokes on with error: ERROR: invalid input syntax for uuid.

It would be nice if there was an extension point such that this guessing logic can be altered for custom types.

Example

Maybe we could creating a factory service which can be decorated for the ORMQueryBuilderLoader? Such that a custom implementation can be provided?
