Hi Peter,

I tried it. I took a pg_dumpall from a 13 cluster after the
regression tests, ran 002_pg_upgrade.pl on master with it, and then
ran amcheck on the upgraded cluster. Without the patch amcheck
complains with the following. With the patch it is clean.

`ERROR:  index "ctl_bpchar" metapage incorrectly indicates that deduplication is safe`

Thanks,
Shihao
