About \ds behaviour, I think to add 2 columns :
- 'LastValue'
- 'Increment'
That would make the command a great deal slower, since it would have to
access each sequence to get that info. I don't object to adding such
columns to \ds+, but I don't think it's a good idea to put them in the
basic command.
Ok.
The other problem you're going to have here is that there is in fact no
such command as "\ds" (nor "\ds+"); rather, it's a special case of
\dtsvi. As such, putting any relkind-specific info into the result is
problematic. I think you're going to have to invent a different command
if you want there to be sequence-specific columns.
Yes, that's why I plan to create a new function listSequences() and
call it from src/bin/psql/command.c :
+ /* \d* commands */
+ else if (cmd[0] == 'd')
+ {
...
+ case 's':
+ success = listSequences(pattern, show_verbose);
+ break;
What happens if the user does this:
\dis
Hmm...
'According' to Terry Prachett,that is probably short hand for telling
the backend to go to Hell = 'dis' is apparently another name for 'Hell'!
(In his book 'Truth', commander Vimes has a personal dis-organiser - as
the 'dis-organiser' is run by a demon from Hell.)
Now back to more appropriate comments...
