The pgsql doco mentions that there is no create group command, at least in
v6.5.2. Further, that one needs to insert directly into the system table
pg_group which is fine.
So I retrieved the user id's I needed from pg_user and made the following
insert.
insert into pg_group(groname, grosysid, grolist) values('dba',50,'{102,101,100}');
Now I want to determine which group(s) a certain user is in. So I tried.
select groname from pg_group pg
where pg.grolist{} = 101;
Which doesn't work, nor does..
select groname from pg_group pg
where pg.grolist[] = 101;
As well as many other combinations I tried. Too many to list and I'm
obviously on the wrong path.
However, provided I know where that user id is in the list ie. second, the
query works. This is not what I want because I'm not necessarily going to
know where that user id is in the list. So how do I write the query in a
general way given just the user id and not its position?
A way around is to make 3 entries for the above insert and therefore the
user id will always be the first and only item in the list, but I don't
want to have to resort to that.
