Обсуждение: BUG #7741: Two bugs when backing up databases with default privileges defined on public schema

The following bug has been logged on the website:

Bug reference:      7741
Logged by:          Nathan Alden, Sr.
Email address:      me@nathanalden.com
PostgreSQL version: 9.2.2
Operating system:   Windows 7 x64
Description:        =


- Create new group role called my_group with default settings
- Create a new database called test_database with default settings
- Run the following SQL:

alter default privileges in schema public grant all on tables to my_group;
alter default privileges in schema public grant all on functions to
my_group;
alter default privileges in schema public grant all on sequences to
my_group;
alter default privileges in schema public grant all on types to my_group;

- Using pgAdmin III, backup the test_database database using the plain
format and note the error. Here's the log:

C:/Program Files/PostgreSQL/9.2/bin\pg_dump.exe --host localhost --port 5432
--username "postgres" --no-password  --format plain --verbose --file
"D:\Databases\PostgreSQL Backups\test_database.backup" "test_database"

Process returned exit code 1.

- Again in pgAdmin III, right-click the public schema and choose Properties
- Navigate to the Default Privileges tab and note how no default privileges
show up, even though they are present

Hmm ... looks like whoever added GRANT ON TYPES did a pretty half-baked
job.  Will look into it --- thanks for the report!

This may be a consequence of the other problem, but in case it isn't,
you should report it on the pgadmin mailing list.  pgsql-bugs generally
just deals with bugs in the core Postgres distribution.

Ugh ... there were more creepy-crawlies under that rock than I expected.
I've squashed a bunch of them:
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=6cb8c6043ee47ced46da131bc0705e9c4bdd8667
but I wouldn't really want to bet that I didn't miss anything.  If you
have the ability to apply patches locally, please apply that one and
keep testing.  If not, I'd recommend staying away from datatype
privileges until 9.2.3 is out ...
