Fix failure to reset <application>libpq</application>'s state fully
between connection attempts (Tom Lane)
</para>
<para>
An unprivileged user of <filename>dblink</filename>
or <filename>postgres_fdw</filename> could bypass the checks intended
to prevent use of server-side credentials, such as
a <filename>~/.pgpass</filename> file owned by the operating-system
user running the server. Servers allowing peer authentication on
local connections are particularly vulnerable. Other attacks such
as SQL injection into a <filename>postgres_fdw</filename> session
are also possible.
Attacking <filename>postgres_fdw</filename> in this way requires the
ability to create a foreign server object with selected connection
parameters, but any user with access to <filename>dblink</filename>
could exploit the problem.
In general, an attacker with the ability to select the connection
parameters for a <application>libpq</application>-using application
could cause mischief, though other plausible attack scenarios are
harder to think of.
Our thanks to Andrew Krasichkov for reporting this issue.

Erroneous expansion of an updatable view could lead to crashes

Furthermore, this bug could be leveraged to allow updates of columns

privileges for some other column(s) of the table.
Any user could also use it for disclosure of server memory.
