There's something broken about your logging setup then, because the
postmaster will most definitely tell you why it's not starting:
$ postmaster -B 16
postmaster: The number of buffers (-B) must be at least twice the number of allowed connections (-N) and at least 16.
$ postmaster -B 32
postmaster: The number of buffers (-B) must be at least twice the number of allowed connections (-N) and at least 16.
$
Without having looked at the code, I think that these very-early-startup
messages may only get sent to stderr and not syslog; so take another
look at what you're doing with the postmaster's stderr.
