+ <title>Migration to version 8.0.3</title>
+
+ <para>
+ A dump/restore is not required for those running 8.0.X. However,
+ it is one possible way of handling two significant security problems
+ that have been found in the initial contents of 8.0.X system
+ catalogs. A dump/initdb/reload sequence using 8.0.3's initdb will
+ automatically correct these problems.
+ </para>
+
+ <para>
+ The larger security problem is that the built-in character set encoding
+ conversion functions can be invoked from SQL commands by unprivileged
+ users, but the functions were not designed for such use and are not
+ secure against malicious choices of arguments. The fix involves changing
+ the declared parameter list of these functions so that they can no longer
+ be invoked from SQL commands. (This does not affect their normal use
+ by the encoding conversion machinery.)
+ </para>
+
+ <para>
+ The lesser problem is that the <filename>contrib/tsearch2</> module
+ creates several functions that are misdeclared to return
+ <type>internal</> when they do not accept <type>internal</> arguments.
+ This breaks type safety for all functions using <type>internal</>
+ arguments.
+ </para>
+
+ <para>
+ It is strongly recommended that all installations repair these errors,
+ either by initdb or by following the manual repair procedure given
+ below. The errors at least allow unprivileged database users to crash
+ their server process, and may allow unprivileged users to gain the
+ privileges of a database superuser.
+ </para>
+
+ <para>
+ If you wish not to do an initdb, perform the same manual repair
+ procedures shown in the <link linkend="release-7-4-8">7.4.8 release
+ notes</link>.

+ If you wish not to do an initdb, perform the following procedures instead.

+BEGIN;
+UPDATE pg_proc SET proargtypes[3] = 'internal'::regtype
+WHERE pronamespace = 11 AND pronargs = 5
+ AND proargtypes[2] = 'cstring'::regtype;
+-- The command should report having updated 90 rows;
+-- if not, rollback and investigate instead of committing!

+ template databases then any subsequently created databases will contain
+ the same errors. <literal>template1</> can be fixed in the same way

+<programlisting>
+UPDATE pg_database SET datallowconn = true WHERE datname = 'template0';

+ Next connect to <literal>template0</> and perform the above repair
+ procedures. Finally, do
