SQL has existed since 1970. Surely this is absurd namespace pollution?
Calling a program "sql" is somewhere in a spectrum between calling
a program "www" and calling a program "server". No point in that
spectrum makes much sense.
And the parallel to parallel seems tenuous at best, indeed
it seems limited to it being able to be called in parallel in order to
drop tables.
(... Which makes me wonder when GNU Parallel will include GNU rm?
And will you make it slower, broken, and divert the regular one without
warning the packages you break, like you did with moreutils and
ikiwiki-hosting? Oh, pardon the rant ...)
