Just for clarity: In the documentation
(http://www.postgresql.org/docs/8.4/static/functions-matching.html#FUNCTIONS-POSIX-REGEXP)
is mentioned "Flag g causes the function to find each match in the
string, not only the first one, and return a row for each such match. "
So in your example it was only matching \r so A\n\tB was returned
Cheers,
Bastiaan
