-------------------------------------------
[~zstan], as I see, you removed "Docs Required" flag. May you elaborate, why we
don't need to update documentation accordingly?
> Drop 'COLUMN IF (NOT) EXISTS' syntax support.

> Let's drop supporting ambiguous "COLUMN IF (NOT) EXISTS" syntax.
> Motivation.
> "IF EXISTS/IF NOT EXISTS" clause is not a part of SQL standard.
> It usage looks ambiguous when statement contains multiple actions for
> adding/dropping multiple columns. Multiple actions support is desirable due
> to performance reasons.
