Dear Group, Please help me if you can. I am in a the most gravest situation. here I read the bug report : https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143208 reason: I got error when i tried \dt relation "pg_catalog.pg_user" does not exist. After reading some responses Comment#21 and Comment#22 (I have no clue why I am getting that error and no idea about SELinux). I tried the following: $sudo /etc/rc.d/init.d/postgresql stop $ psql -d mrnatest psql: could not connect to server: S Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? $ sudo rm -rf /var/lib/pgsql/data $ sudo /sbin/restorecon -R /var/lib/pgsql $ sudo /etc/rc.d/init.d/postgresql start Initializing database: [ OK ] Starting postgresql service: [ OK ] $ psql -d mir-test psql: FATAL: database "mrnatest" does not exist $ psql -d arraydb psql: FATAL: database "arraydb" does not exist I am very much worried and I feel blood is not running any more in me. Please folks, tell me if something is really wrong. The reason I donot have a backup also is that, my pg_dump is not working. when pg_dump'ed my database I created 0 bits file. Very eagerly looking forward for some help...please.. thanks --- Srinivas Iyyer <srini_iyyer_bio@xxxxxxxxx> wrote: > *** Apologies for re-posting this e-mail **** > > Dear group, > I have a strange problem. apologies if this is the > wrong place, however as a first option i am posting > here.
