Warnings for deterministic ordering

[roji]

In split query, and also a stronger note in the pagination page.

Closes #3242

[smitpatel]

There is no issue of deterministic ordering.

[roji]

@smitpatel then please propose another warning text, I don't mind.

[smitpatel]

We already discussed that in teams chat.

[roji]

I pushed this commit as a result of that discussion, believing that's what you wanted. If it isn't, just propose whatever you think is right.

[smitpatel]

Pagination queries without explicit ordering causes non-deterministic result set is right. (though non-pagination page should mention pagination, we discussed that pagination doesn't required to mentioned on the page which talks about pagination). But the main issue remains, there is no non-deterministic ordering, there is only non-deterministic result set.

If you want me to update the message, just assign the issue to me. I will get around to it at some point.

But the main issue remains, there is no non-deterministic ordering, there is only non-deterministic result set.

I don't see it that way: a query whose orderings can produce different resultsets (because of lack of a unique column) can be said to have non-deterministic ordering.

But I'll close this and let you deal with this whichever way you want.
