Database connection bug

[Aramis172]

Please bear with me, as this is the first bug I post and English is not my first language. Having said that, the file etebase-server.ini is generated without taking into account the environment variable corresponding to the "db_host". It just takes a default value, I don't remember if it is "postgres" or "database", but if your postgres container has a different host it will fail with a connection error. I manually corrected the file, and everything went fine after that. I just want you to know about it.
