Would you like apple pie as well?
This is what I would can "an unfortunate joke". I bet it wasn't meant to
be aggressive, but perhaps was misplaced.
I welcome you to Linux, Lazarus and this newsgroup.
Now, going back to the task at hand.

Have you already successfully created a Lazarus Database Application
that conects to a simple database like DBase or SQLite? This is the
first step, then you can go for PostgreSQL.
The most basic component is TDbf and is the best documented one. You can
find it´s tutorial here:
http://wiki.lazarus.freepascal.org/index.php/Lazarus_Tdbf_Tutorial
I recommend that you create first a program that uses TDbf and then
switch to Postgre.
The data-aware components represent fields and are connected by the
correct setting of properties to a TDataSource, witch represents a table
and is also connected to the database components, be it TPSQLDatabase,
TSQLiteDataSet or something else.
So if you create a database program with TDbf and wish to change to
another database system you only need to delete the TDbf component you
dropped on the form, drop a new database component and change the
property on the DataSource to point to the new database system.

Yes, that is what the components are made for.
Did you try looking at the wiki? It is located here:

Do you have difficulty understanding english? I can write for you in
portuguese (suposing this is your mother tongue).
I do have a database program and can send you. It works with SQLite. The
comments are in portuguese. Is it ok for you? I just have to take a look
at it to make sure it works before sending it.
thanks,
Felipe
