+Section 1:      Installing Postgres95
+----------------------------------------------------------------------
+
+1.1)    What extra items do I need to install Postgres95 under Irix?
+
+        You *must* have the following installed:
+        a) Gnu make (installed as gmake)
+
+        You are recommended to install the following:
+        a) GNU install (installed as ginstall)
+
+        You may choose to install the following:
+        a) GNU readline library (if you wish psql to have readline
+           support).
+        b) tcl/tk (if you wish to compile pgtclsh)
+
+1.2)    What changes do I need to make to src/Makefile.global?
+
+        You *must* set the following variables:
+                PORTNAME=       irix5
+                IPCSDIR=        /usr/sbin
+
+        You will also need to change the following to match your own
+        installation:
+                SRCDIR
+                POSTGRESDIR
+
+        If you switch on the USE_TCL option, you will need to set these:
+                TCL_INCDIR= 
+                TCL_LIBDIR= 
+                TCL_LIB = 
+                TK_INCDIR=
+                TK_LIBDIR=
+                TK_LIB =
+
+        You may also make any other changes you need as documented in
+        the INSTALL file and in Makefile.global
+
+1.3)    What are the references in X11_LIB to libsocket and libnsl in
+        src/Makefile.global?
+
+        This was a problem in 1.08 (they are Sun Solaris specific). 
+        It is fixed in 1.09.
+
+1.4)    Are there any other changes I should make?
+
+        If you have installed the GNU install program (ginstall), you
+        should edit src/mk/port/postgres.mk.irix5
+        and change the line:
+                INSTALL=/usr/bin/X11/bsdinst
+        to
+                INSTALL=ginstall
+
+        For an explanation as to why this is a good idea, see Question 2.1
+
+

+Section 2:      Deinstalling Postgres95
+----------------------------------------------------------------------
+
+2.1)    Why can't I move the executable files?
+
+        By default, the IRIX port uses the BSD compatible version of
+        install from /usr/bin/X11. If you read the man page for this
+        version of install, you will see that it is not meant for
+        end-user use; it has the interesting side-effect of chowning
+        files it installs to root.
+
+        You should still be able to delete the files as you (the
+        postgres user) will own the directory in which they are
+        stored.
+
+        The normal IRIX install program cannot be used easily as it
+        takes its arguments in the reverse order. It is therefore
+        recommended to use the GNU version of install (ginstall).
+        See Question 1.4

+Section 3:      Extending Postgres95
+----------------------------------------------------------------------
+3.1)    How do I compile a C program to create a function for extending
+        Postgres95
+
+        Here is a sample command line:
+
+        cc -I/usr/local/postgres95/include/ -I/usr/local/postgres95/src/backend 
+                -shared -o funcs.so funcs.c
