"client" install doesn't install one necessary header file

I did a full build of postgres 7.1.2 on FreeBSD, and then went to do a
client install on a few front-end servers. The INSTALL file says to
do this:

gmake -C src/bin install
gmake -C src/interfaces install
gmake -C doc install

However, this doesn't let you build additional client apps on these
systems since libpq-fe.h does an include of posgres_ext.h.

For example, building DBD::Pg errors out like this:

In file included from Pg.h:17,
from Pg.xs:13:
/usr/local/pgsql/include/libpq-fe.h:27: postgres_ext.h: No such file or directory
gmake: *** [Pg.o] Error 1

Copying the file src/include/postgres_ext.h into
/usr/local/pgsql/include allows the build to complete.

I propose adding the command

cp src/include/postgres_ext.h /usr/local/pgsql/include

to the "Client-only" install instructions. It doesn't seem necessary
to install all of src/include.
