Looks fine.

Thanks! I've committed this with a few changes, mostly:

• Name package 'repmgr' as it can be built against multiple postgresql versions.
• Use tabs in Makefile and reformat some sections.
• Remove duplicate PGUSER creation, that's handled by postgresql*-server.
• Add some more required dependencies (creating a fresh sandbox before building is a good way to show up any that are missing).
