That depends on what performance you're looking for. You'll have to
provide considerably more information until we can help you. You might
want to check this:
https://wiki.postgresql.org/wiki/Slow_Query_Questions
You have not provided the full query, just a query apparently
referencing views, so that the actual query is way more complicated.
Also, plain EXPLAIN is not really sufficient, we need EXPLAIN ANALYZE.
