POSTGRESQL BUG REPORT TEMPLATE
============================================================================
Your name : Bernhard Weisshuhn

Category : runtime: front-end
Severity : serious
Summary: pg_dump sets quotes wrong when dumping groups-acls.
System Configuration
--------------------
Operating System : Linux 2.0.36 ELF
PostgreSQL version : 6.4.2
Compiler used : gcc 2.7.2.3
Hardware:
---------
Redhat 5.2, custom-built postgresql (no RPM)
Versions of other tools:
------------------------
n/a
--------------------------------------------------------------------------
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,
so it treats "group testgroup" as a user.
Sorry, this one is too hard for me to fix the right way,
maybe we could just check, if the userstring begins with
'group ' and alter the quotes accordingly, but this does
not look like a clean solution to me.
