Thread: autovacuum_work_mem and maintenance_work_mem

for default autovacuum_work_mem used the amount of memory RAM from maintenance_work_mem but what will happen if decide to increase the amount of memory RAM on autovacuum_work_mem for instance on 2GB , maintenance_work_mem has 1GB memory RAM and my server has 16GB memory RAM, I ask if it's good idea  that autovacuum_work_mem will use memory RAM independent to maintenance_work_me.
