I've got around this limitation using strings, but I do find it suprising,
that Postgres handles arrays this way.
Searching an array in an WHERE IN clause would be a useful task. (namely for
passing arrays of values between stored functions)

Ok it could be confusing, but I think a number of other DBs employ it to
good effect.

I'll take a look at the array extension in contrib - it sounds useful.

Thanks.
