ActiveRecord#explain with support for EXPLAIN ANALYZE

Extends ActiveRecord#explain with support for EXPLAIN ANALYZE and output formats of JSON, XML, and YAML.

What's EXPLAIN ANALYZE? PostgreSQL devises a query plan for each query it receives. Choosing the right plan to match the query structure and the properties of the data is absolutely critical for good performance, so the system includes a complex planner that tries to choose good plans. One can use the EXPLAIN command to see what query plan the planner creates for any query. With EXPLAIN ANALYZE, EXPLAIN actually executes the query, and then displays the true row counts and true run time accumulated within each plan node.
