Screencasts for PostgreSQL

I recently viewed a screen-cast on PostgreSQL developed by
Peepcode.com and obtained a few really valuable insights respecting
full text searches.  These were things that I was dimly aware of but
that extensive reading had not revealed to me ( lacking as I am in
the imagination necessary ).

I was wondering if any here know of similar presentations on
PostgreSQL usage and administration that might be available to me. 
Free is good but I am willing to pay a reasonable fee for such
things as I did for the material from Peepcode.

Any suggestions?
