Rails - Aug 2009 - Postgresql schema support

Good day,

Reading this
http://weblog.rubyonrails.org/2009/4/24/this-week-in-edge-rails

I understand the structure   ''schema.table_name'' for
postgresql is
supported in Rails 2.3.x

but I''m still having errors like relation "schema.table_name"
doesn''t
exists

Any idea?

Best regards,
Ilya Dyoshin
