I would document the optional VACUUM_OPTS on the page of pg_upgrade.
If Peter thinks it is fine to not do so, that's fine for me as well.
It seems to me that the latest patch sent is incorrect for multiple
reasons:
1) You still enforce -j to use the number of jobs that the caller of
pg_upgrade provides, and we agreed that both things are separate
concepts upthread, no? What has been suggested by Alvaro is to add a
comment so as one can use VACUUM_OPTS with -j optionally, instead of
suggesting a full-fledged vacuumdb command which depends on what
pg_upgrade uses. So there is no actual need for the if/else
complication business.
2) Perhaps we need to worry about the second vacuumdb --all command,
which may want custom options, which are not necessarily the same as
the options of the first command? I don't think we need to care as it
applies only to an upgraded cluster using something older 8.4, just
wondering..
