Further update to my WAL experimentation. pg_xlog files have increased
to 81, and checking today up to 84. Currently nothing much going on with
the server save a background process running a select every 30 seconds
with almost no impact (according to IO from vmstats).
This in itself is a good sign - an improvement on running last week, but
I'd still like to get clarification on WAL file usage if possible.
Log file tailing has nothing more interesting than a whole set of
"recycled transaction log file" entries :
2004-03-01 16:01:55 DEBUG: recycled transaction log file 0000007100000017
2004-03-01 16:07:01 DEBUG: recycled transaction log file 0000007100000018

2004-03-01 16:52:54 DEBUG: recycled transaction log file 000000710000001E
2004-03-01 17:03:05 DEBUG: recycled transaction log file 000000710000001F
Looks kinda automated, but the times aren't quite even at around 6-10
minutes apart.
cheers,
