Yeah, that's what it looks like. This:

is part of the old tsearch2 stuff, and you'll need to remove it from
the v10 installation before you can upgrade.

What I can't tell from this evidence is whether you'd ever converted
tsearch2 into an actual extension --- if you had, then "drop extension"
would be enough to get rid of it. Otherwise, you need to consult a copy
of the old "uninstall_tsearch2.sql" script to find out what you ought to
get rid of.

If you have user tables or indexes that depend on the old tsearch2
objects, things get more complex :-( --- you'd want to update those
to depend on the newer core datatype and index opclasses before
you clean out the old ones.
