PostgreSQL registry entries for apt-get/yum/rpm install

Dear Sirs,

Apologizes, if this is a duplicate question.

Would like to request you to share your valuable inputs on this. I would
like to know the PostgreSQL registry entries when we install it through
apt-get/yum/rpm. I mean, when we install the EnterpriseDB PostgreSQL one
click installer, it creates a registry file as "/etc/postgres-reg.ini" with
the entries like "Port, Data directory, Superuser, e.t.c ..". Does
apt-get/yum/rpm based postgresql installation creates the same kind of
registry file. If so, would you mind to share the details about the
location of those files.

Thanks in advance.

Regards,
Dinesh
