Security Fix(es) :

  - It was found that some selectivity estimation functions
    did not check user privileges before providing
    information from pg_statistic, possibly leaking
    information. A non-administrative database user could
    use this flaw to steal some information from tables they
    are otherwise not allowed to access. (CVE-2017-7484)

  - It was found that the pg_user_mappings view could
    disclose information about user mappings to a foreign
    database to non-administrative database users. A
    database user with USAGE privilege for this mapping
    could, when querying the view, obtain user mapping data,
    such as the username and password used to connect to the
    foreign database. (CVE-2017-7486)"
