Well, if you want to have a CVE for this, you should use a more
complete description.  The actual scenario is that pre-8.2 versions
of the JDBC driver do not know about the "standard_conforming_strings"
option of more recent Postgres servers, and are insecure with *any*
Postgres server in which that option is turned on, which has been
possible since server version 8.2.  What changed in the 9.1 server
is that that option is now on by default.  It's still possible
(and will remain so for the foreseeable future) to turn the option off
in the server configuration, making this and other ancient clients
secure again.  But that isn't the default anymore.
