Hello dialect experts,
what would be the best approach for creating a SqlAlchemy dialect for a new
database system?
Are there any recipes available for this area, or is the way to go to read
code of existing dialects and derive my own dialect from those?
I had a first glance at some built-in
it's a test that very seldom fails in some cases no matter what, as it's
checking reference counts on objects that are expected to be garbage
collected without any cycles. A failure of this test is not strictly a
bug, it just refers to connections or cursors that are not collected

pk = sa.Column(sa.Integer, primary_key=True)
entries = relationship('Entry',
