Yasuo Honda d56a6e19c4 SQLite 3.7.16+ returns the order of the primary key columns
https://www.sqlite.org/releaselog/3_7_16.html

> 9 Enhance the PRAGMA table_info command so that the "pk" column is an increasing integer to show the order of columns in the primary key.

Rails 6 supports SQLite 3.8 then we can remove this skip condition.
