As far as that goes, if you conceptualize it as "wait for this text
to appear in the log file", there's prior art in existing TAP tests.
Basically, sleep for some reasonable short period and check the
log file; if not there, repeat until timeout.
I'm a little dubious that this test case is valuable enough to
mess around with a nonstandard postmaster startup protocol, though.
The main reason I dislike that idea is that any fixes we apply to
the TAP tests' normal postmaster-startup code would almost inevitably
miss fixing this test. IIRC there have been security-related fixes in
that area (e.g. where do we put the postmaster's socket), so I find
that prospect pretty scary.
