I don't know that much about medicine, so this might be a funny
question, but do you really need to know that shots 4 and 5 are
missing,
I want to be able to display shot 4: ... and shot 5: ... in
the application but pull the data from the database, not
calculate it in the

I figured it out, maybe is not the most elegant way but it work for my
case where only small sets are retrieved
create table foo2 (pk int, valor numeric(12,2), porce numeric(5,2));
insert into foo2 values (1,7893.45,0.4);
insert into foo2 values (5,7893.45,0.3);
insert into foo2 values

Having some sort of line numbering in result query would be nice...
The query result has line numbering. How else are you accessing the
individual rows?
Is the issue really that you want psql to number the lines on display?
That could be implemented.

No, but you can easily keep a counter in the client.
How, then, do I do it if I need the row number in a view ?

Here's an example using plperl and global variables. The variables are
local to a session so you don't have to worry about the counters
interfering. If you need two counters in a session, just execute
reset_counter().
CREATE OR REPLACE FUNCTION reset_counter() RETURNS INT AS $$
$_SHARED{counter}

Hello list,
is there a way return a column with the row number automatically
generated according the way the rows were processed by the query.
For instance:
select a,b from foo;
a b
20 yes
40 no
15 yes
to something like:
select counter(),a,b from foo;
counter a b
1 20 yes
2 40 no
3

The OLAP SQL Standard way to spell this is ROW_NUMBER() OVER ().
Postgres doesn't have any support for any of the OLAP features however. It
would be really nice because they're nigh impossible to emulate with
