Hi Pavel,

I noticed just now that variable assignment (i.e., LET) unexpectedly 
(for me anyway) cast the type of the input value. Surely that's wrong? 
The documentation says clearly enough:

'The result must be of the same data type as the session variable.'


Example:

create variable x integer;
let x=1.5;
select x, pg_typeof(x);
  x | pg_typeof
---+-----------
  2 | integer
(1 row)


Is this correct?

If such casts (there are several) are intended then the text of the 
documentation should be changed.

Thanks,

Erik
