I suspect that the main issue you are encountering is that "FROM v_row" is
complaining that v_row is not a known relation.

You really need to provide error messages or your observations in situations
like this. A blanket "does not seem to work" is not enough when asking
others to identify what you are doing wrong. A self-contained example is
even better.

If the above is true then this has nothing with row_to_json other than that
is the function you choose to try and use. A simple "SELECT * FROM v_row"
would get you the same error.
