9.6.9 Default configuration for a default installation but different with-krb-srvnam

Hi,

Currently, when I make select version(), this version is installed.

PostgreSQL 9.6.9 on x86_64-pc-linux-gnu (Ubuntu 9.6.9-2.pgdg16.04+1), compiled by gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609, 64-bit

The database is running on the installation of Ubuntu 16.04 x64

I've configured the GSSAPI authentication with MS Active Directory and it works very well.

The problem is that we have a dev and prod environment and each server must be configured with gssapi again the domain controller. The default user is "postgres" and it cannot be bound to both postgresql server at the same time to the same userPrincipalName on the Windows domain controller.

1. So my question is, how can I compile this version of postgresql (9.6.9) and have the same real things of the default previously installed version, but with the --with-krb-srvnam=POSTGRES_DEV to change the default user name? So one server will have the postgres user and the other one will have postgres_dev user.

2. I'm planning to shut down the postgresql service and then replace files generated by the make install command. After restarting the service, all will work as expected with the same database objects that were running before?

3. Maybe can we configure things differently, if something else can be done to make this work, I'm open to suggestions.

Currently these packages are installed from apt-get install, nothing special except gssapi authentication.
