Pushed. Back-patching turned up one thing I hadn't expected: pre-v12
pg_dump bleated about circular dependencies. It turned out that Peter
had already installed a hack in pg_dump to suppress that complaint in
connection with generated columns, so I improved the comment and
back-patched that too.
I nearly missed the need for that because of all the noise that
check-world emits in pre-v12 branches. We'd discussed back-patching
eb9812f27 at the time, and I think now it's tested enough that doing
so is low risk (or at least, lower risk than the risk of not seeing
a failure). So I think I'll go do that now.
