Hi there!We have a typical data-warehouse type application, and we'd like to set up a star-schema type data analysis software product (which we'll be programming), on top of PG. The goal is to do fast roll-up, drill-down, and drill-through of objects / tables like locations, inventory items, and sales volume.After a few weeks of searching around, we're running into dead-ends on the front-end, and the back-end. PG doesn't support OLAP / MDX .... and the GUI tools that do this, for the most part, require MDX / OLAP (SPSS and DB2, MS SQL Analytics, etc...).What's the PG route here? Are there some secrets / tips / tricks / contrib modules for handling this?--
