Not that I've seen so far, but I did write a related tutorial on building faceted search on top of Django and PostgreSQL a few months ago: https://simonwillison.net/2017/Oct/5/django-postgresql-facet...

you can try https://www.seektable.com which has 'flat table' reports for data browsing and postgresql connector; however this is cloud tool and your DB should be accessible by tool's server. BTW, CSV files are also supported.
