[Buildroot] postgreSQL in buildroot

["Александр Глухов" <alexandrgluhov@mail.ru>]

Hello, I'm using Buildroot for building Linux on my one-boarded computer on the base of freescale i.mx28. And I select postgresql in make menuconfig window. Now I want to configure postgresql, I mean, I want to set database destination, name, username and password, port and create tables in database but I don't know how to do it. And I have not enough experience in it. I tried search config files and tried run initdb and createdb on i.mx28, but unsuccessfully. When I run the i.mx, I get the following messages:
?
Initializing postgresql data base...
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
?
?
The database cluster will be initialized with locale "C".
The default database encoding has accordingly been set to "SQL_ASCII".
The default text search configuration will be set to "english".
?
?
Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
?
?
Success. You can now start the database server using:
?
?
??? /usr/bin/postgres -D /var/lib/pgsql
or
??? /usr/bin/pg_ctl -D /var/lib/pgsql -l logfile start
?
?
done
Starting postgresql: server starting
OK
?
So, it seems, that postgreSQL works, and create database template with user postgres.
I already read documentation, but I still have this problem.
So, could you help me, or advise something, because I have not enough experience to do it by myself.?

With best regards,
Alexandr Glukhov
