Freeze fragment caching related strings

This change freezes the common strings used for fragment caching reducing the string allocations every time a read/write operation is performed on the fragment cache. The patch showed proper object allocation benchmarks showing a noticeable improvement, so it was accepted.

Optimize query for finding primary keys of a Postgres table

This change simplifies and optimizes the query used to determine the primary keys of a PostgreSQL table improving the overall setup time.

Fix generator command for namespaced Rails engines

This change fixes the default generators to create proper namespaced resources for a namespaced Rails engine. For e.g. if we have a namespaced engine bukkits-admin, then

bin/rails g scaffold User name:string age:integer

will now correctly create

admin/app/controllers/bukkits/admin/users_controller.rb.

remove_index method can remove expression indexes now

Now, remove_index method can also be used to remove expression indexes apart from simple column indexes.
