+ When dumping functions or procedural languages from pre-7.3
+ servers, <application>pg_dump</> would

+ Fix <application>pg_dump</> to handle object privileges sanely when

+ </para>
+
+ <para>
+ When dumping functions or procedural languages from pre-7.3
+ servers, <application>pg_dump</> would
+ produce <command>GRANT</>/<command>REVOKE</> commands that revoked the
+ owner's grantable privileges and instead granted all privileges
+ to <literal>PUBLIC</>. Since the privileges involved are
+ just <literal>USAGE</> and <literal>EXECUTE</>, this isn't a security
+ problem, but it's certainly a surprising representation of the older
+ systems' behavior. Fix it to leave the default privilege state alone
+ in these cases.
