In what way exactly? I can't even find the source code on the website. The existing installers are on git.postgresql.org.
Looks like an oversight, we're opening up the repo now.
The other thing to be very careful of is confusing users. Are these distributions interchangeable? What happens if a user tries to upgrade one with the other?
That's the beauty of our update manager, It's consistent across platforms and makes updates a snap. That being said, our testing includes using each set of binaries against data directories created with different installers.
Are you building PL/R ? This is particularly problematic for windows as it requires the same version of R to be on the host system as what was used to build it.
