    <p>I have a production pgsql server with the following stored procedure language support:</p> <ol> <li>internal</li> <li>c</li> <li>sql</li> </ol> <p>I cannot find examples for internal and c, just pl/pgsql or in rare cases sql. I'll try to get the provider to install other languages, but providers usually not provide, so I don't think this will happen... So I am stucked with these languages...</p> <p>Which one should I choose and why? (if you have a good tutorial too, then please write it in your answer or in comment)</p> <pre><code>select * from pg_language </code></pre> <p><img src="https://i.stack.imgur.com/zul78.png" alt="enter image description here"></p> <p>Btw I could not test the c and the internal without tutorial, so maybe there is a simple solution: I cannot use them because they are not trusted.</p> <p><strong>Edit - after the solution</strong></p> <p>The <code>create language</code> what worked for me. After that I checked what languages are available with the following query:</p> <pre><code>select * from pg_pltemplate </code></pre> <p><img src="https://i.stack.imgur.com/EuEMq.png" alt="enter image description here"></p> <p>You can read more about create language <a href="http://www.postgresql.org/docs/8.4/static/sql-createlanguage.html" rel="nofollow noreferrer">here</a>.</p> <p>I will use plpgsql, I found a good book about postgresql here: <a href="http://www.cis.temple.edu/~vasilis/Courses/CS33/Documentation/programmer.pdf" rel="nofollow noreferrer">The PostgreSQL Programmer's Guide , Edited by Thomas Lockhart</a></p>

    1. COAre you *sure* you don't have PL/pgSQL? Sounds strange that a hoster would allow C (which can potentially crash the server) but not PL/pgSQL. And what is "internal" anyway?

    2. COI edited my question. I'll ask them on monday, maybe they'll install pl/pgsql. I don't know what is internal, it is my first day with postgresql and I found nothing about c and internal, that's why I asked...

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.
