Maybe back in 2003 when that message was written...

The OP did join the tables but tried to create an array literal instead of
using a now standard array creation function.  And you do not need to
specify a specific, single, order if you formulate the group by correctly.

You should avoid blindly repeating information, especially if it is more
than a few years old.
