Then David is right, you want load balancing, not CARP high
availability. Look at the pfSense documentation for load balancing.

Thanks David and Thanks Gary.
I spent a lot of time reading and a few things are somewhat becoming
clear.. CARP uses a trusted (preferably dedicated) link to send
heartbeat signals to keep who is alive. This common knowledge enables
some pfsense to stay inactive (to either act as dhcp server or act as
a gateway). When something happens to master next in succession line
takes over.
Very unique and innovative simple.
However most examples are for WAN side traffic and for keeping
internet alive. I will keep trying to find something that shows how
servers can be balanced.
Its amazing because it even keeps the state.

Yes, there are a number of mechanisms that allow this to happen. It
depends entirely on the type of operating system and applications you
are using. Many database server software offer a clustering feature.
Linux has clustering capabilities through a couple of different
facilities. Spend some quality time with Google, I'm sure you'll find
what you need.
