Overhaul the "External Projects" chapter in the manual. Replace
the variabelist with a more concise table, add a URL for each project, remove some orphaned projects, add PL/Py, and various other changes. Initial patch from Robert Treat, subsequent work by Neil Conway.

<productname>PostgreSQL</productname> is a complex software project,

GForge software project and is similar to SourceForge in its feature set. If

GBorg is the original external community developer site, and while it is

currently closed to new projects in favor of PgFoundry, it still contains

it is the primary <application>C</> interface and many other interfaces

are build on top of it. <application>ecpg</> is also packaged because it is

version. All the other interfaces, such as ODBC, Java, Perl, Python, and

others, are external projects and must be installed separately.
