Thanks. I was looking at the recently modified REINDEX syntax and
noticed there another spot for taking an optional name. I ended up
reusing OptSchemaName for that, as in the attached patch. I think
adding production-specific additional productions is pointless and
probably bloats the grammar. So let me +1 your push of the patch you
posted, just to keep things moving forward, but in addition I propose to
later rename OptSchemaName to something more generic and use it in these
three places.
