HS - odd process listing

While playing with HS/SR on -HEAD I noticed that setting
setting max_standby_delay to "-1" leads to the following kind of odd ps
display:

1000 20254 9.2 11.3 8625164 5600644 ? Rs 21:22 1:50
postgres: startup process waiting for max_standby_delay (4294967295 s)

I noticed that a lot of the HS error messages use %u to print integer
parameters. This seemed like a dubious idea to me, but I hadn't made
a concerted effort to get rid of it. Seems like that is what we ought
to do though.
