upgrade the routine's handling of double quotes to match the backend,
in particular support doubled double quotes within quoted identifiers.
Per pgsql-interfaces discussion a couple weeks ago.

domain-constraint patches.  This could be smarter about suppressing
extra parens, but at this stage of the release cycle I want certainty
not cuteness.

discussion on pgsql-hackers: in READ COMMITTED mode we just have to force
a QuerySnapshot update in the trigger, but in SERIALIZABLE mode we have
to run the scan under a current snapshot and then complain if any rows
would be updated/deleted that are not visible in the transaction snapshot.

A couple other minor fixes.

Per gripe from Gaetano Mendola.

invalid (has the wrong magic number) until the build is entirely
complete.  This turns out to cost no additional writes in the normal
case, since we were rewriting the metapage at the end of the process
anyway.  In normal scenarios there's no real gain in security, because
a failed index build would roll back the transaction leaving an unused
index file, but for rebuilding shared system indexes this seems to add
some useful protection.
