  1. new createuser option for replication role

    Fujii Masao <masao.fujii@gmail.com> — 2011-09-10T05:08:05Z

    Hi,
    
    Currently createuser cannot create a role with REPLICATION privilege
    because it doesn't have any option to do that. Which sometimes annoys
    me when setting up replication. I'd like to propose to add new options
    "-x (--replication)" and "-X (--no-replication)" into createuser. "-x" allows
    the new user to do replication, and "-X" disallows. The default is "-X".
    Is it worth creating the patch?
    
    Though I'd like to use "-r" and "-R" as the option name, they have already
    been used for CREATEROLE privilege. So I'm thinking to use "-x" and
    "-X" derived from XLOG. But does anyone have better option name?
    
    Regards,

    Better solution: don't have a short form of the switch.

    That sounds better. I revised the patch so that it adds only "--replication"
    option to createuser.

    Hello
    
    Before doing the complete review, I hit a regression with 9.1 createrole.
    
    the command ''createuser -e -s foo" produce :
      CREATE ROLE foo SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN NOREPLICATION;
    
    before it was:
      CREATE ROLE foo SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN;
    
    The REPLICATION was allowed by default to superuser, and the current
    patch change the default to remove the right.
    
    I believe we should add only the REPLICATION when --replication is
    set, and NOREPLICATION when --no-replication is set.

    Agreed. Attached is the updated version of the patch. It adds two options
    --replication and --no-replication. If neither specified, neither REPLICATION
    nor NOREPLICATION is specified in CREATE ROLE, i.e., in this case,
    replication privilege is granted to only superuser.

    Committed.  Do we need to make any changes in interactive mode, when
    we prompt?  In theory this could be either wanted or not wanted for
    either superusers or non-superusers, but I'm not really sure it's
    worth it, and I certainly don't want the command to go into
    interactive mode just because neither --replication nor
    --no-replication was specified.
    
    Thoughts?

    I believe the intereactive mode is useless.
    
    There is still an issue with the patch for the documentation: a
    superuser, even with NOREPLICATION is allowed to perform
    pg_start_backup() and pg_stop_backup().

    noise, sorry
    I've just read the commited patch which fixed that.

    Agreed. I think that a majority of "createuser" users are not interested
    in REPLICATION privilege yet.
