You should probably take a look at http://htsql.org/ It is free open source software intended for "accidental programmers" -- people who want to pull summarized data from a database without learning SQL or needing rigorous training. Its development was partially funded by grants from foundations, including the National Science Foundation. It does support PostgreSQL and most definitely support counts, sums, etc. In fact, it can automagically give you pretty summary graphs with the ability to drill down to supporting detail. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
