  1. 9.2: Describing a security barrier view in psql

    Dean Rasheed <dean.a.rasheed@gmail.com> — 2012-09-03T09:17:26Z

    Hi,
    
    Unless I'm missing something, it is not possible in psql to tell
    whether a view has the security_barrier option. I think that this is
    something that ought to be possible from psql, otherwise the new
    feature is not visible.
    
    This patch displays any reloptions for a view at the end, if \d+ is
    used, in the same way as for tables.
    
    Sorry if this is too late for 9.2. I really only just noticed this,
    despite playing with security barrier views for a while.
    
    Regards,
    Dean

    Seems to me we should include this into 9.2, since the security_barrier
    feature exists there.  It's not quite too late.  Any objections?
    
    I'd be inclined to go about it a bit differently though: rather than
    duplicating the code, in a way that's *still* wrong the next time we
    enable reloptions for a new relkind, I think we should just pull the
    reloptions-printing code block out of where it is and print reloptions
    regardless of relkind, if verbose and there are some.  This would have
    the effect of switching the order of the tablespace and reloptions
    footers when both are present, but that doesn't bother me any - the
    existing order is only a historical artifact anyway AFAIK.

    +1, I was about to suggest that myself.
    
    Haven't reviewed the code, I'm talking about the principle. I think it
    can almost be considered a bugfix for the security_barrier feature.

    Yes that makes sense. I was just going for the minimal quick fix.
