Tom Lane 88c803457a Improve pg_upgrade's checks for required executables.
Don't insist on pg_dumpall and psql being present in the old cluster,
since they are not needed.  Do insist on pg_resetxlog being present
(in both old and new), since we need it.  Also check for pg_config,
but only in the new cluster.  Remove the useless attempt to call
pg_config in the old cluster; we don't need to know the old value of
--pkglibdir.  (In the case of a stripped-down migration installation
there might be nothing there to look at anyway, so any future change
that might reintroduce that need would have to be considered carefully.)

Per my attempts to build a minimal previous-version installation to support
pg_upgrade.

The PostgreSQL contrib tree
---------------------------

This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly because
they address a limited audience or are too experimental to be part of
the main source tree.  This does not preclude their usefulness.

User documentation for each module appears in the main SGML documentation.

Most items can be built with `gmake all' and installed with
`gmake install' in the usual fashion, after you have run the `configure'
script in the top-level directory.  Some directories supply new
user-defined functions, operators, or types.  In these cases, after you have
installed the files you need to register the new entities in the database
system by running the commands in the supplied .sql file.  For example,

	$ psql -d dbname -f module.sql

See the PostgreSQL documentation for more information about this
procedure.
