Thanks! This works for me. After looking at it, it seemed to me that
listing the autovacuum launcher is perfectly adapted, so we might as
well do it; and add verbiage about it to the autovacuum entry. (I was
first adding a whole new glossary entry for it, but it seemed overkill.)

I also ended up adding an entry for WAL sender -- seems to round things
nicely.

... In doing so I noticed that the definition for startup process and
WAL receiver is slightly wrong. WAL receiver only receives, it doesn't
replay; it is always the startup process the one that replays. So I
changed that too.

What do you think?

PS: I almost want to add a note to the startup process entry, something
like "(The name is historical: it refers to its task before the
introduction of replication, when it was only related to the server
starting up after a crash.)"

PPS: Do we want the list to be in alphabetical order, or some other
order?
