Is this feasible with Node.js + PG? 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. -- Michael -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
