Make sure pg_rewind can't run as root

mhagander · mhagander · commit 5d5aeddabfe0 · 2018-04-09T21:33:33.000+02:00
Previously a warning was printed, but the tool actually kept running
even when running as root. This is something we definitely want to
prevent, but since this means a behavior change, not backpatching.
