Unfortunately there is no more than the man page and the sgml file
distributed with PostgreSQL. I just didn't find the time to write more.

To the best of my knowledge this is incorrect syntax. For instance Oracle
says:

   The SELECT statement associated with the cursor cannot include an INTO
   clause. Rather, the INTO clause and list of output host variables are
   part of the FETCH statement.

I cannot find the text in the standard right now, but there also only FETCH
is listed with INTO.

Please correct me if I'm wrong.
