Linux kernel is moving to use -Os everywhere. AFAIK their argument is

This also seems to hint that -Os is not really appropriate to
Postgres.
Although it would be good fit for eg. PgBouncer.
while it might be right in case of linux kernel (which I won't agree
totally with personally), I don't see any reason to compare it with
postgresql.
Kernel is extensively use by everything in system, hence their
reasoning. Postgresql is an application.
