Обсуждение: search for groups with a user

I have to search for which groups a certain user is in. I found out that the 
field grolist is of type INT[] (array of integers with reference to the 
uids). To search through the array I need a module which is in contrib/array, 
which I found, but how do I use it? What do I have to do to be able to do 
searches on arrays in the WHERE clause?

Saludos... :-)

In postgresq-7.0.3, I did:

cd contrib/array
make
make install

[I'm not certain the following is necessary, but if you get errors it might fix things]
psql -d yourdb -f array_iterator.sql
[or whereever install put it]


Then, just try something like:
select groname from pg_group g, pg_user uwhere g.grolist *= u.usesysid and       u.usename = 'young' ; groname   
------------supervisororiginatoroperator
(3 rows)

showing that I'm in those three groups.


I hope this helps,-- George

Reboot now?  [OK]

This didn't work, but I got it to work, compiling by hand (gcc and ld).

Until I found it in the docs.... :-)
