Hi @michbeck and @dereuromark ! If you're interested by this PR, could you help me with the tests errors (8.2, pgsql) please ? I'm not sure to find the cause easily. Maybe a problem saving a book [here] ?(https://github.com/propelorm/Propel2/blob/4f36eea97eb5fcf451a4f80430a728be92b70ac8/tests/Propel/Tests/Runtime/ActiveQuery/ExistsTest.php#L254)

Thanks for any help !

@PhilinTv this can be closed too I think. You can already specify the type (see #1971).
