* Improve account counters handling * Use ActiveRecord::Base::sanitize_sql to pass values instead of interpolating them Keep using string interpolation for `key` as it is safe and using “ActiveRecord::Base::sanitize_sql_hash_for_assignment” would require stitching bits of SQL in a way that is not more easily checked for safety. * Add migration hook to catch PostgreSQL versions earlier than 9.5
