This seems the cleanest way of fixing its lack of a shutdown callback,
which was preventing it from working correctly in a query that didn't
run it to completion.  Per bug report from Szima GÄbor.

the postmaster directly, thereby ensuring that only the postmaster's direct
parent shell will be a postgres-owned process.  In combination these should
fix the longstanding problem of the postmaster sometimes refusing to start
during reboot because it thinks the old lockfile is not stale.

table, same as CREATE INDEX, plus an exclusive lock on the specific index
being processed.

for 'could not obtain lock' so that applications will be able to detect
that case cleanly.

improvement in usability and reduction in grammar size.

a separate production func_expr.  This allows us to accept all these
variants in the backwards-compatible syntax for creating a functional
index; which beats documenting exactly which things work and which don't.
Interestingly, it also seems to make the generated state machine a little
bit smaller.
