*	Deduplicate various Active Record schema cache structures	Jean Boussier	2019-06-03	1	-0/+29
	Real world database schemas contain a lot of duplicated data. Some column names like `id`, `created_at` etc can easily be repeated hundreds of times. Same for SqlTypeMetada, most database will contain only a limited number of possible combinations. This result in a lot of wasted memory. The idea here is to make these data sctructures immutable, use a registry to substitute similar instances with pre-existing ones.
