Shridhar has a good point using nice. I know RedHat supports nice
because I have installed a totally background program that uses "nice
19" as part of its command line.
I just successfully tried this on a RedHat 7.3:
nice -n 15 pg_dumpall >testdump.sql
It seems to work. However, my SQL server is so lightly loaded I cannot
verify that it actually *helps*.
