I may be a bit off , but can you try a couple of things, other than a fresh install, incase you have time to debug more.
is it possible to snapshot the vm, and and set it up in a controlled environment where you can play around with incoming connections at the network layer
beyond the vm.
With that, is it possible for you to use gdb and debug a connection to the postmaster.
you can setup using below,
and then you can put a breakpoint at this function and check the input lines it gets for parsing.
but maybe this helps identify why other ips are being allowed.
to be more paranoid, you can all reject from the ip you are trying to make a connection, and trace that specific rule.
this might be an overkill and maybe a waste of effort given you already can query the hba view, but incase you want to try out.
