Answer my own question here:  the drive Yeb got was the brand spanking 
new OCZ Vertex 2 Pro, selling for $649 at Newegg for example:  
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227535 and with 
the supercacitor listed right in the main production specifications 
there.  This is officially the first inexpensive (relatively) SSD with a 
battery-backed write cache built into it.  If Yeb's test results prove 
it works as it's supposed to under PostgreSQL, I'll be happy to finally 
have a moderately priced SSD I can recommend to people for database 
use.  And I fear I'll be out of excuses to avoid buying one as a toy for 
my home system.
