Address pools for NAT: What happens when the pool runs out

When you have no more addresses in the pool, will pfSense do overloading as with using a single address?

Based on the lack of information that was provided, yes. It gives the NAT process more addresses to source from.

So if you have an address pool of 8 addresses, and 8 local users connect to the internet, I can configure the system so that these first 8 all get a different public address?
And then, when the ninth user connects to the internet he gets to share a public address with one of the first 8 users?

The standard outbound NAT in pfSense is not a 1:1 mapping, multiple LAN clients will be using the same external address and rotated in round-robin fashion if multiple external addresses are available. There is no such thing as pool running out of addresses.
