Hi Daniele, thanks for your effort.

After reading the docs i have a question about the parameters in the 
'in' clause.

In psycopg2 i do:

  params = (1,2,3,4)
  cursor.execute("select * from mytable where field1 in %s", (params,))

or

  params = ('black','red','green')
  cursor.execute("select * from mytable where field2 in %s", (params,))

What will it be like in psycopg3, will it be the same?, will I have to 
create a special adapter?

Thanks
