Hi All, I'm looking for advice for optimizing the pg_dump portion of "pg_upgrade --link". Since this schema only dump can't take advantage of parallel processing with jobs I'm looking for any preparation or configuration settings that can improve speed. 9.2 to 9.6 CentOS 6/64bit 512GB I see only one CPU of 32 doing anything and it's often at 100%. Disk IO is minimal. Memory use varies but always plenty to spare.
"pg_dump --schema-only" is single-threaded. -- Angular momentum makes the world go 'round.
