Hi,
I'm a bit confused as to the logic of nulls. I understand that null
is to represent an unknown value. So it makes sense that the result
of tacking an unknown value onto a known one is unknown, because you
don't know what exactly you just tacked on. So
select null::text || 'hello';

Probably. We couldn't even handle nulls within arrays until a release
or two ago. I wouldn't be surprised if someone comes up with a proposal
to make null-array handling a bit more
