    If  fact,  it  isn't  a  problem  at  all.  The only data any
    PostgreSQL DBA would ever pump into a restore is something he
    built  himself  or  something  he  got  from a secure source,
    right? I mean, you don't feed some unknown script  you  found
    on  the  net into the DB as the PostgreSQL superuser. In that
    case, someone doesn't need to hand-craft such bad  compressed
    data,  he  can simply use the \! functionality of psql in his
    script to do whatever he wants as user postgres.
