NULLs and sort order

...

Or am I expected to submit a patch on the Docbook sources?

...

"Expected"? No. But it sure would be preferable since you would get it
the way you think it should be, and others could spend time on other
things.

An alternative, if you are not comfortable diving into sgml markup, is
to find the place in the sgml where the changes should be, but just put
them in without markup. Someone else like Peter or myself would be happy
to fix up the markup.

Attached is a small patch for the Reference Manual which adds
information about nulls and sort order.

This is based on information obtained from Peter Eisentraut and
Tom Lane on pgsql-hackers.

Please check my English and Docbook markup, as both are a second
language to me.

I guess it should be in "ORDER BY Clause" of "SELECT" in the
Reference Manual, and in the 7.2 release notes.

Can someone add this to the documentation?

Currently the JDBC driver says:
- Backend >= 7.2 sorts nulls higher than any other value in a
domain. In other words: ascending means nulls at the end,
descending means nulls at the start.
- Backend < 7.2 puts nulls at the end regardless of sort order.

That is correct.
