====== PostgreSQL ======


Using pgAdmin 3 you can import a database using the command line: 

\i <database path>

You access the commandline through Plugins > Console.

Alternatively, you can of course use the bash shell as well:

<code>
psql DATABASE_NAME < DUMP_FILE
</code>

(You also have the option to specify the user: ''psql -U PSQL_USER DATABASE_NAME < DUMP_FILE'')


If you're having problems with connecting your Moodle to your database you should consider adding 
the port of the database behind the host string in the config.php, like this: 

$CFG->host = 'localhost:**5433**'

===== phpPgAdmin =====

Just like MySQL has phpmyadmin, PostgreSQL has its own web-based tool: phpPgAdmin. Under Ubuntu, installing it should be easy:

<code>
sudo apt-get install phppgadmin
</code>

The tool should now be available under ''http://localhost/phpPgAdmin''. You might run into trouble however, if your php settings display too many notices and warnings. To suppress this, edit ''/usr/share/phppgadmin/conf/config.inc.php''. Add this code to the top of the file:

<code>
// per Ubuntu bug 614481
error_reporting(E_ALL & ~E_DEPRECATED);
</code>

... and you should be good to go.

===== SchemaSpy =====

Use schemaSpy to graph tables: http://schemaspy.sourceforge.net/ (not just for PostgreSQL; a lot of other databases are supported too).

Download the jdbc driver for PostgreSQL here: http://jdbc.postgresql.org/download.html

(use ''java -version'' to check what jvm version you've got)

<code>
onno@solin-amd64:~/schemaspy$ java -jar schemaSpy.jar -t pgsql -db nuon_clean -host localhost:5432 -u onno -o /home/onno/temp/schema -i "(.*quiz.*)|(.*question.*)" -dp postgresql-9.1-902.jdbc4.jar -p PASSWORD -s public -hq
</code>

(''-hq'' is high quality graphics)
