What about the query:

select 't','78','Here is a value' as stringfield, testname from tbltest

This gives you three Unknown fields. PostgreSQL can't know that the
first is to be a bool or that the second is to be an int until you
actually give it a type. Usually via casting or by inserting into a
table/

Single quotes denote an untyped constant, not a string.

Hope this helps,
