Revoke - database does not exist
Hi,
Do not seem to figure out what is wrong here. Why am I getting database does not exist. I just created the database and am able to connect to it as "postgres" user.
I am trying to restrict "testuser" from connecting to "myDB" database.
Thanks in advance.
postgres@ulinux3:~$ createuser -D -S -R -P testuser
Enter password for new role:
Enter it again:
postgres@ulinux3:~$ createdb myDB
postgres@ulinux3:~$ psql
psql (9.3.4)
Type "help" for help.
postgres=# REVOKE ALL PRIVILEGES ON DATABASE myDB FROM testuser;
ERROR: database "mydb" does not exist
postgres=# \q
postgres@ulinux3:~$ psql myDB
psql (9.3.4)
Type "help" for help.
myDB=# REVOKE ALL PRIVILEGES ON DATABASE myDB FROM testuser;
ERROR: database "mydb" does not exist

Thomas is likely correct about the quoting. The command programs are
case-sensitive and perform the proper quoting for you when issuing commands;
but when you are inside psql you need to take care to perform the proper
quoting yourself.
WRT grant/revoke keep in mind when you revoke you only remove pre-existing
grants; it does not establish an explicit block on its own. i.e., it
doesn't stop default permissions, or those inherited from PUBLIC, from
applying. You would need to remove those inheritance-granted permissions
and then explicitly grant them back to those who still require them while
omitting those that do not.
