I'm confused by this.
The point of the patch is to highlight to the user that even though
he/she does "pg_upgrade -j 8" the "-j 8" option isn't passed down to
vacuumdb.
Default value is 1, so in that case the echo command doesn't highlight
that fact, otherwise it is. The user can then cancel the script and use
the suggested command line.
The script then executes the vaccumdb command with the $VACUUMDB_OPTS
argument as noted in the documentation.
Sample script attached as well.
I added extra space in the --analyze-in-stages part.
Kirk, can you provide a delta patch to match what you are thinking ?
Best regards,
Jesper
