Getting one row for each subquery row...?

Howdy:

Running PostgreSQL 7.2.1 on RedHat Linux 7.2.

I have a table where I'm the owner, but I want to give
all permission to another person. So, I do a
'grant all on <table> to <joe_user>' and it seems that
they have all the rights that I do.

But they are not able to add a comment to the table.

Is this a table creator-only ability? How can I give
the new person the ability to add a comment to
the table?

Thanks!

adding comments to a tableHi All,
here are my three tables. I wold like to list them in the following way: I need all the columns from t_stockchanges, and one field for the pgoductgroup the t_stockchanges.productid belongs to.

But one product can belong to many group, so i would need one row for each group for each product.

My bad query is:
------------------------
DB=# select t_stockchanges.productid, (select name from t_productgroups where id=(select productgroupid from t_prod_in_pgr where productid=t_stockchanges.productid)) as pgroup from t_stockchanges;
ERROR: More than one tuple returned by a subselect used as an expression.
DB=#
---------------
Yes, this is absolutelly true, but I would like postgres to give me all the tuples found. How can I ask him to do so?

Thank you,
-- Csaba

Use the IN instead of = and this will allow Postgres to return more than
one row in the sub-select
