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. 

Thanks - Richard
