[postgis-users] biggest rectangle contained within another polygon

[tommaso]

Hello, I need to calculate the biggest rectangle which is contained 
within another polygon. A sort of inner envelope or inner bounding box.
I found this interesting article: 
http://cgm.cs.mcgill.ca/~athens/cs507/Projects/2003/DanielSud/
Is it possible in Postgis?

I have attached a picture with a example of what I need.
Tom
