This sounds like a nice thing to fix.

> Problem Description:
> --------------------
> When executing
> % pg_dump -z somedatabase
> and a database contains acl-permissions like
> => "GRANT ALL on sometable to group somegroup"
> pg_dump incorrectly generates the line:
> GRANT ALL on "sometable" to "group somegroup";
> instead of
> GRANT ALL on "sometable" to group "bosses";
>
> The incorrect output generates errors when restoring
> databases from the dump and fails to set the correct
> permissions.

> Test Case:
> ----------
> createdb grouptestdb;
> psql grouptestdb -c "insert into pg_group (groname,grosysid,grolist) VALUES ('testgroup',1000,'{500}');"
> psql grouptestdb -c "create table dummy (foobar int4);"
> psql grouptestdb -c "grant ALL on dummy to group testgroup;"
> pg_dump -z -s -t dummy grouptestdb

> Solution:

> Obviously, pg_dump does not seem to know about groups at all,
