30176f2 introduced a bulk: true option to MySQL adapter's change_table,
which aggregates multiple column changes into a single complex ALTER TABLE
statement. This change extends the feature to PostgreSQL.

Considerations

  • MySQL's bulk_change_table lives in
    ConnectionAdapters::AbstractMysqlAdapter, perhaps these methods should be
    moved to ConnectionAdapters::PostgreSQLAdapter?

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

This repository is being automatically checked for code quality issues using Code Climate. You can see results for this analysis in the PR status below. Newly introduced issues should be fixed before a Pull Request is considered ready to review.

Looks great!

As discussed, I think we can ultimately unify bulk_change_table so it only needs to live in abstract, but this looks good as is, and sets us up perfectly for that step.
