    <p>Just restore to a different database. For <code>pg_restore</code> of <code>-Fc</code> dumps from <code>pg_dump</code>'s custom format:</p> <pre><code>createdb newdbname pg_restore --dbname newdbname database.dump </code></pre> <p>For SQL-format dumps <em>not</em> created with the <code>-C</code> option to <code>pg_dump</code>:</p> <pre><code>createdb newdbname psql -f database_dump.sql newdbname </code></pre> <p>If you're streaming the dump from a remote host, just omit <code>-f database_dump.sql</code> as the dump data is coming from stdin.</p> <p>You can't easily <code>CREATE DATABASE</code> in the same command as your restore, because you need to connect to a different DB like <code>template1</code> in order to create the new DB. So in your example you might:</p> <pre><code>psql -h localhost -U localadmin template1 -c 'CREATE DATABASE newdb;' pg_dump -U remoteuser -h remoteServer dbname | psql -h localhost -U localadmin newdb </code></pre> <p>Note the omission of the <code>-C</code> flag to <code>pg_dump</code>.</p> <p>The first command is just the longhand way of writing <code>createdb -h localhost -U localadmin newdb</code>.</p> <hr> <p><strong>Update</strong>: If you're stuck with a <code>pg_dump</code> created with the <code>-C</code> flag you can indeed just <code>sed</code> the dump so long as you're extremely careful. There should only be four lines (one a comment) at the start of the file that refer to the database name. For the database name "regress" dumped with Pg 9.1's <code>pg_dump -C</code>:</p> <pre><code>-- -- Name: regress; Type: DATABASE; Schema: -; Owner: craig -- CREATE DATABASE regress WITH TEMPLATE = template0 ENCODING = 'UTF8' LC_COLLATE = 'en_US.UTF-8' LC_CTYPE = 'en_US.UTF-8'; ALTER DATABASE regress OWNER TO craig; \connect regress </code></pre> <p>This can be transformed quite safely with three (or four if you want to rewrite the comment) very specific <code>sed</code> commands. Do <em>not</em> just do a global find and replace on the database name, though.</p> <pre><code>sed \ -e 's/^CREATE DATABASE regress/CREATE DATABASE newdbname/' \ -e 's/^ALTER DATABASE regress/ALTER DATABASE newdbname/' \ -e 's/^\\connect regress/\\connect newdbname/' \ -e 's/^--Name: regress/--Name: newdbname/' </code></pre> <p>This should be a last resort; it's much better to just dump without <code>-C</code>.</p>

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.
