 They are renamed to _create_record and _update_record respectively.
 Closes #11645
PostgreSQL and SQLite, remove varchar limit. [Vladimir Sazhin & Toms Mikoss & Yves Senn]

There is no reason for the PG adapter to have a default limit of 255 on :string
columns. See this snippet from the PG docs:

    Tip: There is no performance difference among these three types, apart
    from increased storage space when using the blank-padded type, and a
    few extra CPU cycles to check the length when storing into a
    length-constrained column. While character(n) has performance
    advantages in some other database systems, there is no such advantage
    in PostgreSQL; in fact character(n) is usually the slowest of the
    three because of its additional storage costs. In most situations text
    or character varying should be used instead.
test, show current adapter behavior for `add_column limit: nil`.

This is an illustration of https://github.com/rails/rails/pull/13435#issuecomment-33789752
Removing the limit from the PG and SQLite adapter solves the issue.
MySQL is still affected by the issue.
