To really test it, you need a PostgreSQL server. However, you can do a
very limited, but still meaningful, test without it:

 - Menu: File / New / Database

 - Connect to an existing database: PostgreSQL

 - Next

 - Datasource URL: host=localhost

 - Next

 - User name: blank

 - Test connection -> the error message should be along the lines of:

   Couldn't establish database connection to 'sdbc:postgresql:host=localhost'
   could not connect to server: Connection refused
   is the server running on host "localhost" (::1) and accepting
   TCP/IP connections on port 5432?
   could not connect to server: Connection refused
   is the server running on host "localhost" (127.0.0.1) and accepting
   TCP/IP connections on port 5432?

   If you get any other error message (such as "no driver registered
   for URL"), then there is something wrong with PostgreSQL-SDBC or
   LibreOffice more generally. I you get the error message only with
   127.0.0.1 and not with ::1, that's fine and not a problem.

 - OK to click error message away

 - next

 - no, do not register the database

 - uncheck "open the database for editing"

 - finish

 - choose a filename to save file to

 - save

 - close libreoffice

 - open libreoffice again, open file you just created

 - in the left part of the main screen, click "tables"

   You should get the same error message as above with "test
   connection". If not, it is a problem.



As to installing a PostgreSQL server, rather easy on Debian GNU/Linux
and probably most other distros. Make sure you get version 8.4 or
later.

aptitude install postgresql
sudo -u postgres createdb -O $USER name_you_choose "$USER's test DB"
psql --db name_you_choose
CREATE TABLE "names" ( num serial, name varchar(30) NOT NULL, PRIMARY KEY (num) );
# It says:
# NOTICE:  CREATE TABLE will create implicit sequence "names_num_seq" for serial column "names.num"
# NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "names_pkey" for table "names"
# CREATE TABLE
INSERT INTO "names" (name) VALUES ('Alice'), ('Bob'), ('Eve'), ('Mallory');
INSERT INTO "names" (num, name) VALUES (0, 'Nominem incognitum');
\q
#back to the shell

Now, do as above in LibreOffice, except put:

Datasource URL: host=localhost dbname=name_you_choose
User name: Your UNIX username
Do *not* check "needs password".

You'll see in tables the "names" table. You can double-click on it and
modify data, insert new data, delete row, etc.
