Hello,
RFE: Consider that you want to run pg_upgrade via some script with some
default '-o' option. But then you also want to give the script's user a
chance to specify the old-server's options according user's needs.
Then something like the following is not possible:
$ cat script
...
pg_upgrade ... -o 'sth' $PG_UPGRADE_OPT ...
...
I know that this problem is still script-able, but the fix should be
innocent and it would simplify things. Thanks for considering,
Pavel
