Hi,
> We have been seeing intermittent aggressive use of SWAP space by PostgreSQL despite availability of HUGE amounts of free RAM. We have a 100 GB database with 256 GB RAM on the server so there is no shortage of RAM nor shortage in PostgreSQL buffer cache. Our swappiness setting is set to “1”.

Please provide your postgresql.conf.
Also, why do you need a swap on such a setup? I seriously doubt that
it serves any purpose.
