The following bug has been logged online: Bug reference: 4916 Logged by: Richard Neill Email address: rn...@cam.ac.uk PostgreSQL version: 8.4 Operating system: Linux Description: wish: more statistical functions (median, percentiles etc) Details:
In addition to the existing aggregate functions (avg, stddev etc), it would be nice if postgres could return further information. For example, the quartiles, percentiles, and median. [mode would also be useful, as an explicit function, though we can get it easily enough using count(1) order by count desc]. According to google, this has been a wish since at least year 2000 for various people, but doesn't seem to be implemented.
