The extra shared memory allows PostgreSQL to cache more and perform better. 
It's mostly for production servers. It shouldn't have any adverse effects on 
the Mac. If it's the same setting I'm thinking of, then all it does is 
increase the amount of shared ram a single application can use. If it does 
mess anything up, then just delete the /etc/sysctl.conf file and when you 
reboot, the file will be rebuilt by the Mac to its default settings 
automatically.
