While implementing a method to retrieve the permissions on a table, the statement: "grant all on test to public;" kills the backend. -- Peter T Mount petermount@earthling.net or pmount@maidast.demon.co.uk Main Homepage: http://www.demon.co.uk/finder Work Homepage: http://www.maidstone.gov.uk Work EMail: peter@maidstone.gov.uk

I've just resynced with cvs, rebuilt from scratch and still:
test=> \z
Database = test
+------------------+----------------------------------------------------+
| Relation | Grant/Revoke Permissions |
+------------------+----------------------------------------------------+
| test | |
+------------------+----------------------------------------------------+
test=> grant all on test to pmount;
PQexec() -- Request was sent to backend, but backend closed the channel
before responding.
This probably means the backend terminated abnormally before or
while processing the request.
This happens both with and without the large object patch, so that's ruled
out.
Platform: Linux 2.0.27

Can you give me a test case? Is it \z on an empty database, or does a
table have to have a specific permissoin?
---------------------------------------------------------------------------
test=> \z
Database = test
+------------------+----------------------------------------------------+
| Relation | Grant/Revoke Permissions |
+------------------+----------------------------------------------------+
| test | {"=arwR","wilson=arwR"} |
| test2 | |
| test3 | |
| test4 | |

One of the methods in JDBC's DatabaseMetaData returns details about the rights granted on the database, so to test the method, I was setting up the normal user with update rights to the table, so I had something to work on. The backend simply dies when ever the grant statement is entered correctly. -- Peter T Mount petermount@earthling.net or pmount@maidast.demon.co.uk Main Homepage: http://www.demon.co.uk/finder Work Homepage: http://www.maidstone.gov.uk Work EMail: peter@maidstone.gov.uk

If I understood the test case you published, you are specifying to the grant
command the database "test", not a table within the database. The man page for
grant is not very specific, but is this supposed to work?

The man page for > grant is not very specific, but is this supposed to work? No, there is a table called test, that I'm granting permissions to. The database is also called test. Could grant be confusing the two? -- Peter T Mount petermount@earthling.net or pmount@maidast.demon.co.uk Main Homepage: http://www.demon.co.uk/finder Work Homepage: http://www.maidstone.gov.uk Work EMail: peter@maidstone.gov.uk
