Problem about initdb

After many trials, I do not yet understand the problem that occurs me
when I execute "initdb -l /usr/lib/pgsql -r post -d" on my system.
I report the output below:

Running with debug mode on.
initdb: using /usr/lib/pgsql/local1_template1.bki.source as input to
create the template database.
initdb: using /usr/lib/pgsql/global1.bki.source as input to create the
global classes.
initdb: using /usr/lib/pgsql/pg_hba.conf.sample as the host-based
authentication control file.

We are initializing the database system with username costa (uid=10103).
This user will own all the files and must also own the server process.
