Yeah, we also have start_bgworker(). I agree that we should rename
things so that they make as much sense as possible.
In the current code, we have this:
StartOneBackgroundWorker() in postmaster.c
start_bgworker() in postmaster.c
do_start_bgworker() in postmaster.c
With this patch we would have
StartOneBackgroundWorker() in postmaster.c
start_bgworker() in postmaster.c
StartBackgroundWorker() in bgworker.c
I think we should rename to something like this:
maybe_start_bgworker() in postmaster.c
do_start_bgworker() in postmaster.c
StartBackgroundWorker() in bgworker.c
(I would also rename the functions in 9.3 to avoid inconsistency). Not
wedded to those particular names, but (1) I would add the "maybe" prefix
because that's what that function does; and (2) it seems to me that
stuff in bgworker.c tend to use CamelCaseNaming and postmaster.c uses
names_with_stuffed_underscores.
(My convention tends to be that "internal" stuff uses underscores while
exposed APIs use CamelCase. I probably fail to do it really
consistently.)
