Explore contents of WAL files

Explore contents of WAL files

Hi all,
     I've done a ton of searching for a solution to this several times 
before, but never found anything that could help.

I need to take a look at what is inside a WAL file, perhaps not exactly 
everything in it, even a summary would be nice (such as how many 
transactions or types of activity).

I've looked at xlogviewer and xlogdump, but it seems those projects have 
been abandoned since later 2006. The latest version they report support 
for is 8.2.

Are there any tools out there that would work with WAL files from a 8.4 
cluster on a 64 bit machine?

Thanks in advance,
     Brian F
