If you want to install the fixes in the information schema
concerning the bit types, you need to reload the information
schema. This is either accomplished by initializing a new cluster
by running <command>initdb</command>, or by running the following
sequence of SQL commands in each database (ideally including
<literal>template1</literal>) as a superuser in
<application>psql</application>, after installing the new release:
<programlisting>
DROP SCHEMA information_schema CASCADE;
\i /usr/local/pgsql/share/information_schema.sql
</programlisting>
Substitute your installation path in the second command.
