    <p>I'm a postgreSQL newbie and I can't find any usable introduction to using the psql command. At least I think that's the command I want to use.</p> <p>Is it possible in postgreSQL to simply connect to the server and then list, create, use and examine databases?</p> <p>I'd like to be able to use psql to do something like this with MySQL (I've deleted many extra lines):</p> <p>Connect without specifying a database - I can't seem to do that with psql:</p> <pre><code>$ mysql -u root -prootpassword Welcome to the MySQL monitor. Commands end with ; or \g. Server version: 5.5.28 MySQL Community Server (GPL) </code></pre> <p>I can list databases with mysql but the posgreSQL command SHOW doesn't seem to do it.</p> <pre><code>mysql&gt; show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | ocdp | | performance_schema | | test | +--------------------+ 5 rows in set (0.04 sec) </code></pre> <p>I can switch databases. </p> <pre><code>mysql&gt; use ocdp; Database changed </code></pre> <p>I can't figure out this command in psql:</p> <pre><code>mysql&gt; show tables; +---------------------------------+ | Tables_in_ocdp | +---------------------------------+ | OCAddresses | | OCStreets | +---------------------------------+ 2 rows in set (0.00 sec) </code></pre> <p>I think I can do this in psql with 'createdb' and 'dropdb' commands:</p> <pre><code>mysql&gt; create database foo; Query OK, 1 row affected (0.00 sec) mysql&gt; drop database foo; Query OK, 0 rows affected (0.03 sec) </code></pre> <p>I use \quit</p> <pre><code>mysql&gt; quit Bye </code></pre> <p>The answer to these questions should take only a moment for someone who knows postgreSQL but I just can't find documentation anywhere that shows how to do these simple operations. Maybe I shouldn't even be using psql at all for this?</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.
