Well, the use case is someone using tsearch2 on version A and wants to
a do a dump to restore into later version B. It would be helpful if
pg_dump compacted the whole tsearch2 infrastrcutre into a single
"INSTALL tsearch2" command. Obviously, the tsearch2 uninstall script
for version B isn't going to work properly for a database restore from
version A. And this way a dump/restore will pickup any new features
added in the later version.

That's true, but it's something to keep in mind.
Have a nice day,
