Actually ... after further thought it seems like maybe we should
make this more like other cases rather than less so. ISTM that much
of the issue here is somebody's decision that "TO version" should be
offered as a completion of "UPDATE", which is unlike the way we do this
anywhere else --- the usual thing is to offer "UPDATE TO" as a single
completion. So I'm thinking about the attached.

This behaves a little differently from the old code. In v14,
alter extension pg_trgm upd<TAB>
gives you
alter extension pg_trgm update<space>
and another <TAB> produces
alter extension pg_trgm update TO "1.

With this,
alter extension pg_trgm upd<TAB>
gives you
alter extension pg_trgm update to<space>
and another <TAB> produces
alter extension pg_trgm update to "1.

That seems more consistent with other cases, and it's the same
number of <TAB> presses.
