This is probably a search_path problem.  You've got an index expression
somewhere with a SQL function that is not being careful about which
schema(s) to look for "unaccent()" in.  There were security fixes to
restrict the search path that VACUUM/ANALYZE runs with, which breaks
functions that aren't careful about that.
