Two .sql files would be pointless. Remember we're talking about the C
function names, not the SQL names; the only time the user should notice
the difference is when restoring an old dump.
As I see it there are three options:
1) do nothing; keep the existing C function names. dump/restore from
older versions will still work, but new functionality won't be
available without messing with the SQL.
2) hard cutover; rename all the dubious C functions. dump/restore from
older versions will get lots of errors, for which the workaround will
be "install the new hstore.sql into the database before trying to
restore".
3) some sort of compatibility hack involving optionally duplicating the
names in the C module.
