There was likely no strong intention to follow make on this. A small problem would be that getopt doesn't portably support single-letter options with optional arguments. The main problem, however, is that make -j is pretty useless and dangerous. Using it on a large parallel-make-safe project can easily lock up (thrash) your machine. make -j together with -l (--load-average) is kind of useful, I guess, but exactly how "load average" translated to a PostgreSQL database system is to be determined. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
