Text supports up to 16 megabytes, not 2

See the requireField method that defines it as mediumtext.

@anselmdk, thanks for your PR! By analyzing the blame information on this pull request, I identified @chillu and @sminnee to be potential reviewers

[chillu]

Can you please check if that's the case in the other supported databases as well? Postgres, SQLite, MSSQL

[tractorcow]

I'd rather remove the size constraint at all; It's not correct to declare db-level storage limitations at the orm level.

[assertchris]

Agree with @tractorcow - removing these constraints (yet keeping the ability to constrain) seems like a good idea to me.

[anselmdk]

I agree that making them configurable would be the best option. Maybe just through config.yml.

[sminnee]

This discussion is completely unrelated to the PR which is correcting some docs.

Removing these constraints requires a patch to MySQL.

I've confirmed that the limit is 16mb on MSSQL. I can't get clarity on PostgreSQL's limits; as best I can see it's unrestricted. SQLite has a 1gb limit.

I'm merging this and closing the PR.
