pgAdmin 1.8 online documentation
pgAdmin III's functionality can be further enhanced using the adminpack contrib module for PostgreSQL. This is a library of additional functions that may be installed on your server which allows pgAdmin to offer additional features, such as:
The adminpack is installed and activated by default if you are running the 'official' pgInstaller distribution of PostgreSQL for Windows, however, if you are running any other version of PostgreSQL you will need to manually install it. To do so, simply copy the /xtra/admin or /xtra/admin81 (for PostgreSQL 8.1 and above) directory from the pgAdmin source distribution to the /contrib directory of your pre-configured PostgreSQL source tree. If you don't have the pgAdmin source code, you can download the adminpacks here.
Run the following commands (substituting admin for admin81 if required):
# cd $PGSRC/contrib/admin # make all # make install
The module should now be built, and installed into your existing PostgreSQL installation. to be used, you must now install the module into the database you use as pgAdmin's Maintenance DB (normally postgres, though you may wish to use a different database). To do so, locate the admin.sql or admin81.sql file installed in the previous step - normally this may be found in /usr/local/pgsql/share/contrib/ and run it against your database. You will normally need to do this as the PostgreSQL superuser:
$ psql postgres < /usr/local/pgsql/share/contrib/admin.sql
The next time you connect to the server with pgAdmin, it will detect the presence of the adminpack and offer full functionality.
