How difficult would it be to allow attribute names to be aliased when inheriting: CREATE TABLE base ( oldtag TEXT ); CREATE TABLE derived ( more_attrib INT4 ) INHERITS(base) -- WITH base.oldtag AS derived.newtag So that SELECT * from derived newtag | more_attrib -------+----------- der#1 | derived value #1 and SELECT * from base* oldtag ------ base #1 der #1 Thoughts? Is this _that_ bad of an idea. I think it would really help to manage aggregation complexity. I suppose this is a big project hunh? Thanks! Clark Evans

It seems like a horrible idea to me ;-). The point of inheritance
is that whatever else your derived class may be, it *IS A* parent-
class object as well, and anything that works on the parent class
will work on the subclass. In your example,SELECT more_attrib FROM base where oldtag = something;
would work butSELECT more_attrib FROM derived where oldtag = something;
would fail. That's not my idea of a derived class.
It's not clear exactly what you want to accomplish here, but I
wonder whether inheritance is the right model for the relationships
among the tables in your database at all. It seems like you are
trying to force-fit some other kind of relationship into the
inheritance model.

I like the look better, but (putting on my graphics-guy hat) that GIF
is *huge*. 175K is a tad of an excessive download for a web-page
frammish. Also it doesn't look very good if your browser's page
background is not white --- there's a white ring around each
continent thanks to poor antialiasing.
The extent of the dithering makes me think the image was made from a
truecolor original. If so JPEG at a moderately high quality setting
would work better (and look much better on truecolor displays), though
you'd lose the ability to have a transparent background. PNG is also a
possibility if you want to assume that visitors have recent browsers.

175K? It started at 24K, a load/save in xv brings it back to 24K.

Why, so it does --- didn't think to try that. Bruce, are you using
something that outputs "uncompressed GIF" to avoid the LZW patent?
My remarks about dithering and the antialias ring still stand though.

It started at 24K, a load/save in xv brings it back to 24K. Let me look at that. Seems to have grown somehow. It is the transparency that is causing it. I am using 'convert' to add the transparency.

See Magick.tmpl or Makefile.in. I am running 3.8.9. Oh, well, have to wait for a BSD/OS upgrade, or do it myself. Actually, changelog for 3.7.* say: Rather than a separate LZW kit, Image Magic now comes as twodistributions. One with LZW compression and one without(suggested by pederl@norway.hp.com). -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

It's gray on my browser (Netscape 4.0something). Even if it were
cream, the background of the gif is *white* not cream, so the ring
would still be there (maybe a little harder to see though).
Since GIF hasn't got partial transparency, you can't do real
antialiasing without making the background colors match.
You're probably best off not using transparency at all, unless
you forget about antialiasing. (Or is it antialiasing that's
leaving the near-white pixels there? Maybe it's just sloppy drawing
of the border of the transparent region?)

Did you take a look at my one? It's using transparency too,
but since I created the image by program, there are only 4
colors at all (plus tranparent). Has it noise too or is it
O.K.?

If the <BODY> doesn't define a background, Netscape uses it's
(configurable) default one. So your config say's white (why
not slategray?).

It's defined in the style sheet for the page as: #fffdec
