For int2vector and oidvector, I think it boils down to wanting to access
columns like pg_proc.proargtypes without detoasting. We could fix that,
but it'd likely be invasive and not a net positive.

It seems a bit broken that tsquery is marked that way, though; I doubt
we are getting any notational benefit from it.

Dunno about gtsvector.
