Web-based Graphical Query Building Tool for PostgreSQL

Hi all,

My company sells software that uses PostgreSQL and the need has come up to
provide a tool that gives our clients access to query the database but we
don't want to expect these users to be able to use SQL. Is there a product
out there that provides a graphical query builder? Preferably web-based. I
know that Pgadmin as a graphical query building.

Thanks in advance,
Caleb Palmer
