Currently in Postgres SET TABLESPACE always comes with [ NOWAIT ]
option, so I hope it worth adding this option here for convenience.
Added in the new version.

Actually, new_tablespace parameter was documented, but I've added a more
detailed section for SET TABLESPACE too.

Yes, and there is a comment section in the code describing why. There is
a repeatable bunch of checks for verification whether relation movable
or not, so I put it into a separated function --
check_relation_is_movable. However, if we want to do only REINDEX, then
some of them are excess, so the only one RELATION_IS_OTHER_TEMP is used.
Thus, RELATION_IS_OTHER_TEMP is never executed twice, just different
code paths.

OK, changed, although I don't think it is important, since this is the
only one tablespace variable there.
