Graphing PostgreSQL database connections count grouped by database

[omfgppc]

Hello,

I am currently using libzbxpgsql for monitoring postgresql servers and I am mostly happy with how that is working but I can't quite figure out how to graph something like:

SELECT datname, count(*) from pg_stat_activity
AND application_name ~'MyApp'
GROUP BY datname ;

Result for graphing on 2 axis should be:
x0=db1, y0=10
x1=db2, y1=40
x2=db3, y2=2
etc.

Any ideas?
