PostgreSQL version: 7.4

Operating system:   FreeBSD 5.2 (Current)

Description:        unbounded string copy in postmaster

Details:

Looks like the -o command line option doesn't perform any bounds checking on
the option before copying to the ExtraOptions[1024] char array. [line 529 of
postmaster.c]

I cannot get super excited about this, since the person or script
starting the postmaster has to be trusted anyway.  But I've tweaked
the code to prevent a buffer overrun here.
