if there is some no-SQL database supporting ACID + generic queries like a SQL database, I would consider it.

However, the column limit is the problem, no the database. 1200 cols are reasonable for standard problems. Having a Postgresql supporting thousands of columns will be useful in Machine Learning and similar domains.
