Did you use the actual name of the index (in case its actual name differs
from what you showed us in the CREATE INDEX)? If you did and it doesn't
show anything, then I don't think the table has been ANALYZED since the
index was created. Note that ANALYZE and EXPLAIN ANALYZE are different
things. You need to run "ANALYZE assets;" or "VACUUM ANALYZE assets;"
