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.
