Clean up README file a bit.

There won't be any, and in fact there won't even be an RTE for NEW,
which was leading to a core dump in CVS tip.  7.4 and earlier manage
not to crash when applying ResolveNew in this scenario, but I think
it was just good fortune that they didn't.  Per report from
Bernd Helmle.

o "_" is not escaped, and causes TeX to abort, thinking it's a
  subscript outside of maths mode.  Most of my table and field names
  use underscores, so this is a really nasty one.
o The column count is calculated using the contents of opt_align. But
  opt_align has one extra element, and so it's always one too many.  I
  changed it to count the column headings, like all the other output
  formats.  There may be a bug in computing opt_align that this patch
  does not address, but I'm not yet familiar enough with the psql
  source to fix this as well.
o  The line drawing rules for each border setting (0-3) and expanded
  mode didn't always match the documented behaviour and what other
  formats (e.g. aligned) did.  I made it as conformant as possible,
  and also tidied the alignment of the first line of the footer, which
  was incorrectly indented.

This avoids changing the displayed appearance of ACL columns now that
array_out decorates its output with bounds information when the lower
bound isn't one.  Per gripe from Gaetano Mendola.  Note that I did not
force initdb for this, although any database initdb'd in the last
couple of days is going to have some problems.

recommend that people go get Apache's rotatelogs program.  Additional
benefits are that configuration is done through GUC, rather than
externally, and that the postmaster can monitor the log rotator and
restart it after failure (though we certainly hope that won't happen
often).

subarrays of a given dimension have the same number of elements/subarrays.

Also repair a longstanding undocumented (as far as I can see) ability to
explicitly set array bounds in the array literal syntax. It now can
deal properly with negative array indicies. Modify array_out so that
arrays with non-standard lower bounds (i.e. not 1) are output with
the expicit dimension syntax. This fixes a longstanding issue whereby
arrays with non-default lower bounds had them changed to default
after a dump/reload cycle.

Modify regression tests and docs to suit, and add some minimal
documentation regarding the explicit dimension syntax.

real gettext() later on, so it was called twice before.

and documentation to reference 8.0 instead of 7.5.

dependency was looking at wrong columns and so would always fail.
Was not exposed by regression tests because we are only testing cases
involving built-in (pinned) types and so no actual dependency entry
exists to be removed.

datatype.  Per example from Gaetano Mendola, 2004-07-25.

Instead of putting all the OWNER TO commands at the end, it dumps then
after each object.  This is WAY more readable and nice.  ACLs are still
at the end.
