I could find nothing in the documentation regarding this. My guess is that I could support this by subclassing types.TypeDecorator, and adding pre- and post-processing of query parameters (http:// www.sqlalchemy.org/docs/types.myt#types_custom) to convert a python list to and from a string, for example. (I would probably have to use 'eval()' on the way out of the db, though.)
right, theres no DB-specific types built in as of yet, but this array type would be a good candidate for the postgres module. You might have to make a complete subclass of TypeEngine to support this though, as its really a "composite" type and requires different text in a CREATE statement, etc.
might be worthwhile to add a mixin to all PostGres types that allows an "array dimension" parameter to be added. but see how a simple subclassing goes for now.
