Обсуждение: start postmaster as root : problem

 Hi all,

I have to develop an embedded database with PostgreSQL.
I have a Linux Distribuction  that works only in single user mode as root.

The postmaster daemon starts only if  I 'm  not  root user.

Do you have a solution for this problem ??

Thanks.

AFAIK, It's backend/main/main.c that checks the username with geteuid().
If you disable it and re-compile the file, postmaster will not check the
username.

That's about as brain dead a setup as I've ever heard of :-(.
Get a real operating system, not a CP/M emulation.

That's an intentional security measure.  You could defeat it by altering
the source code but we do not recommend doing so.
