[Rails] Re: Changing adapters in ActiveRecord does not change the generated sql

I've found out something very interesting. If I'm first connected to
Postgresql, then switch to Mysql, I can reset both table and column names
properly using

Model.reset_column_information

and

Model.reset_table_name

This gives me the proper backquoted columns/table names for Mysql.

User.scoped.to_sql #=> "SELECT `users`.* FROM `users`"

If however, I switch back to Postgresql, and run the same commands, it
doesn't actually reset the column information properly, only the table_name.

User.scoped.to_sql #=> "SELECT \"users\".* FROM `users`"

I've found that it actually doesn't matter in which order this happens. The
first switch to one adapter allows me to reset properly. The second switch
however does NOT.
