Oops.

Too much with the ol' cut and paste.

I'm happy to send an updated patch but perhaps the committer, assuming the
patch is accepted, would be kind enough to update for me.

Thanks for reviewing.

Patch applied. Thanks.

I originally thought of this as a feature addition, but I realized that
ALTER INDEX is being added because people are going to want to move
tablespaces for indexes, and without this, they can't easily.

Which would fall under adding a feature onto the tablespaces, not fixing a
bug in tablespaces itself ... does *not* having ALTER INDEX *break*
tablespaces? Causes it not to work, or not build?

No, but it is a missing capability many will complain about. I can
easily remove it. I saw no one comment when I added it to the patches
queue.

I hadn't seen you add it to the patches queue ...

I did see Gavin's submission but did not yet have time to look at the
details. What does it *do* exactly --- simply allow INDEX as a
substitute for TABLE in the syntax, or more? I'm not thrilled at the
idea of adding a lot of duplicate coding for this.

I tried to avoid any duplication. The patch still uses all the ALTER TABLE
code. Its just a grammar modification and some setting of completion tags.

That being said, I felt obliged to provide at patch when I started hearing
noise about ALTER TABLE <index name> being a bit of a hack -- which it is.

The issue was that few people currently modify indexes because in the
past you could only rename an index or change its owner. With
tablespaces, we are going to have lots more people moving indexes
around, and I think people were getting confused because there was no
ALTER INDEX to move them.

I can still back it out and leave it for 8.1 but it probably will reduce
confusion and perhaps need for an FAQ, "How do I move an index between
tablespaces?"

FYI, I just fixed a typo in the ALTER INDEX manual page that mentioned
INDEXSPACE instead of TABLESPACE.
