Subject: [PATCH] fix: add --username=postgres to initdb command to ensure
 postgres role exists

The initdb command was creating a superuser with the system username instead
of 'postgres', causing connection failures when the code tried to connect as
the postgres user. Adding --username=postgres explicitly creates the expected
postgres superuser role during database cluster initialization.

Fixes #48
