Rails 5 migration/schema dump issue/question with postgres and OracleEnhancedAdaptor

[John Landes]

I'm using Rails5.0.0.beta3 with multiple database connection, one to postgres and one to Oracle. When I execute rake db:migrate or rake db:schema:dump, an error is generated which appears that the OEA is asking the Postgres adaptor for a listing of it's materialized views. I'm not sure if this is a AR issue or an OEA issue or maybe both? 

$ rake db:schema:dump

rake aborted!

Tasks: TOP => db:schema:dump

If I comment out the OEA in the Gemfile, the db:migrate and db:schema:dump work as expected.
