linux/bsd

Hello all,

I'm in the process of making some decisions as to
what OS I should be using for a product that development
will begin on soon. It's a web based thing using postgres,
apache etc and will be all on one machine.

My question is to what operating system would be a better
one to use for postgres. ie linux/bsd.

I know postgres works fine on both but some opinion
from the postgres developer community as to which OS
they prefer would have a bearing on this decision.

PS sorry in advance for posting a question that might
   spark a lot of opinions.

Thanks
Richard.
