You do realize that the above index has nothing whatever to do with
searches on propertyvalue?  (Or at least not propertyvalue alone.)

My advice is to drop propertyvalue from the index and see what
performance you get.

You could possibly do something with a partial index, eg
    create index ... where length(propertyvalue) < 2000
but that'd probably require modifying your queries, so I suspect it's
not really very practical.
