Feature Description

There is an option to ignore entity when generating migration

@Entity({ synchronize: false })

But there is no such option for @Column().

The Solution

It would be nice to have @Column({ synchronize: false })

Considered Alternatives

I didn't find any alternatives to this

Additional Context

The problem is that I have a column like this one:

  @Column({ insert: false, update: false, select: false })
  fooBar?: boolean;

It's not persisted to DB, I assign a result of custom .addSelect(...) to it.
But when I generate a migration, typeorm treats it as real column and generates ALTER TABLE ... for it.
So I need a mechanism to ignore a column in migration generation.
