Overview
FIXME: this is not used by the adapter anymore, it is here because it is a dependency of old tests that needs to be reviewed

.extension(name, &block) ⇒ Object
Defines an AR-JDBC extension. An extension consists of a declaration using this method and an ArJdbc::XYZ module that contains implementation and overrides for methods in ActiveRecord::ConnectionAdapters::AbstractAdapter. When you declare your extension, you provide a block that detects when a database configured to use the extension is present and loads the necessary code for it. AR-JDBC will patch the code into the base JdbcAdapter by extending an instance of it with your extension module.
+name+ the name of a module to be defined under the +ArJdbc+ module.
+block+ should be a one- or two-arity block that receives the dialect name or driver class name as the first argument, and optionally the whole database configuration hash as a second argument
Example:
ArJdbc.extension :FRoB do |name| if name =~ /frob/i require 'arjdbc/frob' # contains ArJdbc::FRoB true end end
