Обсуждение: Develop item from TODO list
Hello!
We are 2 Students from the Technical University of Vienna. At our internship we would like to develop the item of the TODO list: "Allow SET CONSTRAINTS to be qualified by schema/table name".
Is anyone working on it?
Our research at the SET CONTRAINTS function showed the following Error:
ERROR: cross-database references are not implemented: "schema.table.constraint"
SQL state: 0A000
Is this the problem we could implement?
Approximately where is the point to implement?
As we have few experience with open-source programs, can someone recommend a good C-editor for Ubuntu?
What do others use?
Thanks in advance,
Chris & Viktor

Uh, it was done years ago, AFAICS, unless the Todo entry means something
non-obvious.
regression=# create schema foo;
CREATE SCHEMA
regression=# create table foo.bar (f1 int unique deferrable);
NOTICE: CREATE TABLE / UNIQUE will create implicit index "bar_f1_key" for table "bar"
CREATE TABLE
regression=# set constraints foo.bar_f1_key deferred;
SET CONSTRAINTS
regression=# set constraints foo.bar_f1_key immediate;
SET CONSTRAINTS
regression=#
Bruce, do you remember what that entry was really about?

Thanks for the advice!
Yes, we are new to linux too :)
We have chosen Eclipse, because we have already experience with it.
However, after downloading the code from CVS, we can't build it, because of some include commands in tutorial / complex.c says "No such file or directory". Does anybody know what the clue is?
What should we get, if the code starts?
All the best,
Chris & Viktor

There are quite a few editors out there but here are some that are going
to be a bit more user friendly (in terms of learning curve):
Bluefish
Anjuta
Kate

would suggest Eclipse.

Yep, that was it. I have remove that TODO item. Thanks. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +
Hello!
We have chosen another item from the list:
"Allow ALTER TABLE to change constraint deferrability and actions"
Is this already done? If yes, can you recommend any task which is
appropriate for beginners in open-source software?
Thanks in advance,
Chris & Viktor

Well, I guess letting newcomers know about tools of choice amongst regular contributors is a good idea, but the best editor you can find around is the one you master. In all fairness until now I counted a lot of Emacs users, some (g)vim ones, and I didn't keep track of users of Visual Studio, Eclipse, etc but you can't pretend they're not there. My bet is that the winner in term of user count would be Emacs. Regards, -- dim

I should probably mention that my comment about vi was mostly tongue-in-cheek, although it is my preferred editor just because I've been using it so long (i.e. it's the one I've mastered). I learned emacs at one point, but it was just too slow on the Sun3 I was using at the time, and the need to hit the control key constantly was hard on my hands. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company
