Well, writing a procedure that rebuilds the complete table in Postgres or Oracle is easy as well. I never needed this, but I am sure, there are some sample implementations out there.

Rebuilding the entire table doesn't seem feasible for large tables to begin with. Especially with a lot of incoming and outgoing foreign keys.

I disagree that MySQL is the most "popular".

It might be the "most used" one because of so many web hosting services included it for ages by default.

Tangential, but there are almost certainly more SQLite databases in existence than every other RDBMS put together, probably by 3 or 4 orders of magnitude.

It doesn’t support column reordering either.
