@rxin In order to support sql syntax better and align SQL standards. I
think it is worth to add a numeric type as an alias of decimal.

They are not exactly the same in ANSI SQL, although MS SQL Server looks
like use them interchangeably.

@gatorsmile Is it worth adding a numeric type as an alias of decimal? Both
types seems to be in the SQL standard and some dbms (e.g., postgresql and sql
server) can parse both.
