The server could be changed so as backend processes use setpriority
and getpriority using a GUC parameter, and you could leverage priority
of processes using that. The good news is that this can be done as a
module, see an example from Fujii Masao's pg_cheat_funcs that caught
my attention actually yesterday:
https://github.com/MasaoFujii/pg_cheat_funcs/commit/a39ec1549e2af72bf101da5075c4e12d079f7c5b
The bad news is that you are on RDS, so vendor locking is preventing
you from loading any custom modules.
