I went again through this, and the only real thing I found that there
was a leftover prototype in walsender.h. I've in interim worked on
backpatch versions of that series, annoying conflicts, but nothing
really problematic. The only real difference is adding SetLatch() calls
to HandleWalSndInitStopping() < 9.6, and guarding SetLatch with an if <
9.5.
As an additional patch (based on one by Petr), even though it more
belongs to
http://archives.postgresql.org/message-id/20170421014030.fdzvvvbrz4nckrow%40alap3.anarazel.de
attached is a patch unifying SIGHUP between normal and walsender
backends. This needs to be backpatched all the way. I've also attached
a second patch, again based on Petr's, that unifies SIGHUP handling
across all the remaining backends, but that's something that probably
more appropriate for v11, although I'm still tempted to commit it
earlier.
Michael, Peter, Fujii, is either of you planning to review this? I'm
planning to commit this tomorrow morning PST, unless somebody protest
till then.
