PGXN Client 1.0 released

I am pleased to announce the first release of the PGXN Client.

The PGXN Client is a command line tool designed to interact with the
PostgreSQL Extension Network allowing searching, compiling, installing
and removing extensions in PostgreSQL databases.

For example, to install the "semver" extension, the client can be invoked as:

    $ pgxn install semver

which would download, compile and install the extension libraries for
one of the PostgreSQL servers hosted on the machine and:

    $ pgxn load -d somedb semver

which would load the extension in one of the databases of the server.

To install the client and start playing with PostgreSQL extensions:

    $ sudo easy_install pgxnclient

The project homepage, where you can find complete documentation and
further useful links is at:

    http://pgxnclient.projects.postgresql.org/

The client is designed to be extensible, and the first extensions are
already available, both to help the development of new extensions:

  - PGXN::Meta::Validator By David E. Wheeler:

Many thanks to the members of the PGXN Users group
<https://groups.google.com/group/pgxn-users/> for the invaluable
feedback during the development. Of course further feedback is
welcome! Cheers!
