So it would be grammatical to say

    reindex table test concurrently

or in a pinch

    reindex concurrently table test

but I don't see anything grammatical about

    reindex table concurrently test

(given that the object is "table test").

Where this gets really messy is stuff like this:

    reindex (verbose) database concurrently postgres

Why would "concurrently" not be part of the options next to "verbose"?
