Re: Any Postgress & MySQL experts in the house?

[Andy Davies <dajdavies@xxxxxxxxx>]

Perhaps not the answer you're looking for but...

Have you considered using something the RRDTool (
http://www.mrtg.org/rrdtool/index.en.html)
to store the data instead?

It's built for storing time series data, less resource hungry than MySQL
and
can produce pretty graphs fairly easily.

Cheers
