substring wrong example in manual - Mailing list pgsql-general

In Table 4-6. SQL String Functions and Operators


FUNCTION                RETURN TYPE              DESC
...
substring(              text                     extract
  string                                         substring
  [from integer]
  [for integer])

                        EXAMPLE                  RESULT
                        substring('Thomas'       oma
                        from 2 for 3)
...

The result should be 'hom' instead of 'oma':

       1   2   3   4   5   6
       T   h   o   m   a   s
from   1   2
           ^-------^
for        1   2   3
