Agreed, we've been on 7.2 for a while now because it just works.  
The regex substring introduced in 7.3 was a pretty cool feature, for 
instance, that makes life easy.

then maybe they would be willing to donate some small amount each ($500 or 
so) to pay for backporting issues.  Since mostly what I'd want on an older 
version would be bug / security fixes, that $500 should go a long way 
towards backporting.

I was under the imporession that 7.4 removed the need to reindex caused by 
monotonically increasing index keys, no?

Yeah, I would rather have had more back porting to 7.2 because there were 
tons of little improvements form 7.2 to 7.3 I could have used while 
waiting for 7.4's improved pg_dumpall to come along.
