Body
With PostgreSQL 9.1 or later, installation of additional modules has been simplified. <a href="https://www.postgresql.org/docs/current/interactive/contrib.html" rel="nofollow noreferrer">Registered extensions (including dblink)</a> can be installed with <a href="https://www.postgresql.org/docs/current/interactive/sql-createextension.html" rel="nofollow noreferrer"><code>CREATE EXTENSION</code></a>: <pre><code>CREATE EXTENSION dblink; </code></pre> Installs into your default schema (<code>public</code> by default). Make sure your <a href="https://stackoverflow.com/questions/9067335/how-to-create-table-inside-specific-schema-by-default-in-postgres/9067777#9067777"><code>search_path</code></a> is set properly before you run the command and the schema is visible to all users who have to work with it. Alternatively, you can install to any schema of your choice with: <pre><code>CREATE EXTENSION dblink SCHEMA extensions; </code></pre> See: <ul> <li><a href="https://stackoverflow.com/questions/19146433/best-way-to-install-hstore-on-multiple-schemas-in-a-postgres-database/19146824#19146824">Best way to install hstore on multiple schemas in a Postgres database?</a></li> </ul> Run once per database. Or run it in the standard system database <code>template1</code> to add it to every newly created DB automatically. <a href="https://www.postgresql.org/docs/current/interactive/sql-createextension.html" rel="nofollow noreferrer">Details in the manual.</a> You need to have the files providing the module installed on the server first. For Debian and derivatives this would be the package <a href="https://stackoverflow.com/questions/12100638/error-when-creating-unaccent-extension-on-postgresql/12101055#12101055">postgresql-contrib-9.1</a> - for PostgreSQL 9.1, obviously.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
