Yeah, that seems to be a few versions out of date :-(
The page should probably refer to "strpos", which is the true function
name:
play=> select strpos('high','ig');
strpos
--------
2
(1 row)
You can also use the SQL92 POSITION syntax:
play=> select position('ig' in 'high');
strpos
--------
2
(1 row)
