Hi,

Again, thanks very much for the review.  Here's an updated patch (just
merged against master) fixing most of your comments here.  I couldn't
reproduce previous problems with the attached:

 - DROP EXTENSION was broken, asking to cascade to self
 - CREATE EXTENSION was bypassing "requires"

I could reproduce the second problem then fix it with the following one
liner. I missed it because my test case still fails for not finding the
cube type rather than the cube extension without this fix:

-    if (!OidIsValid(featoid) && !missing_ok)
+    if (!OidIsValid(*featoid) && !missing_ok)

Thank you all for your patience while I was busy elsewhere, it's
definitely not a show stopper in my book :)

dim=# create extension earthdistance;
ERROR:  feature "cube" is not currently provided
HINT:  Please install an extension that provides it first

dim=# create extension cube;
CREATE EXTENSION

dim=# create extension earthdistance;
CREATE EXTENSION

dim=# drop extension cube cascade;
NOTICE:  drop cascades to extension earthdistance
DROP EXTENSION

Fixed.

Well the SGML table describing the catalog has 4 cols :)

Fixed.

Fixed.

Fixed, I guess the English would need rephrasing.

I don't think so.
