Hi all,

I don't understand the last result:

select 'Ho Ho Ho' ~* '^Ho'; returns true
select 'Ho Ho Ho' ~* ' Ho'; returns true
select 'Ho Ho Ho' ~* '[^ ]Ho'; returns false (Please note there is a space between ^ and ])

 From my limited experience of regex, the last one is searching for either
   'Ho' preceeeded by space or
   'Ho' at the beginning of a string.

No, it's searching for not-space, the ^ inverts the meaning of the square brackets. You probably want something like '(^Ho)|( Ho)'
