> In SQL standard 2011 part 7 value expression, it defines the SQL syntax for explicit ROW value constructor to allows all the valid value expreesion:
> {code:sql}
> <row value constructor> ::=
>     <common value expression>
>   | <boolean value expression>
>   | <explicit row value constructor>
> <common value expression> ::=
>     <numeric value expression>
>   | <string value expression>
>   | <datetime value expression>
>   | <interval value expression>
>   | <user-defined type value expression>
>   | <reference value expression>
>   | <collection value expression>
> <explicit row value constructor> ::=
>     <left paren> <row value constructor element> <comma>
>         <row value constructor element list> <right paren>
>   | ROW <left paren> <row value constructor element list> <right paren>
>   | <row subquery>
> <row value constructor element> ::=
>   <value expression>    
> {code}
> I also tried the PostgreSQL 9.6 for the query:
> {code:sql}
> create table t1(
>   f0 int,
>   f1 varchar(20)
> );
> insert into t1 values(1, 'abc');
> -- select row(t1.f0 + 1, t1.f1) from t1; -- outputs (2, abc)
> {code}
