We disable shared_preload_libraries to prevent background workers to
initialize and start during server start in pg_upgrade.

In essence, this is for a similar reason that we use a restricted socket
access from f763b77193b04eba03a1f4ce46df34dc0348419e because background
workers may produce undesired activities during the upgrade.

* [PATCH] Disable background workers during servers start in pg_upgrade

We disable shared_preload_libraries to prevent background workers to
initialize and start during server start in pg_upgrade.

In essence, this is for a similar reason that we use a restricted socket
access from f763b77193b04eba03a1f4ce46df34dc0348419e because background
workers may produce undesired activities during the upgrade.
