Very cool that this will support regular sql queries and queries can be sent using postgresql drivers. Postgresql drivers are super stable and supported everywhere. Driver support is usually overlooked with 'Enterprise' Data Warehousing solutions. I recall that it was really hard to get the Vertica drivers installed and stable under Linux.

I took a few screenshots from the keynote and included one showing the mention of Postgresql and ODBC/JDBC support. Included here if you want to see for yourself: http://wp.me/p2sRpx-1e
