#postgresql_adapter_class ⇒ Object

Everything from this point onwards is a copy-paste or inherit from Rails’ activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb with some changes

The changes besides name changes include:

* ore_64_8_v1_term and ore_64_8_v1 are registered
* column_definitions maps with CipherStashColumnMapper.map_column_definitions

(We can’t just inherit from PostgreSQLAdapter because we cannot load the

postgresql_adapter.rb file; that would load 'pg', and we cannot [right
now] have both 'cipherstash-pg' and 'pg' loaded at the same time.)
