(Side question entirely unrelated as I'm reading that..)
What's your magic recipe for showing up with commit format? The best
thing I could come up with was to use "(14,trunc)%H" in format.pretty,
but it has the idea of showing two dots at the end of the commit ID.

No issues with ba08edb0654.

FWIW, Debian Search reports that the only references to BackgroundPsql
are in the Postgres tree, so backpatching 70291a3c66e does not worry
me. Github has more much references due to forked code or direct
copies of BackgroundPsql.pn modified for the purpose of the code.
