Can you point me to documentation about the pcache logging subsystem?
slapd -d pcache
Indeed, I can't find any mention of it in obvious places (slapo-pcache(5), admin guide under pcache overlay, loglevel directive in slapd.conf(5) or slapd-config(5)). I suggest you file a request for documentation update.

I tried that and slapd didn't recognize it. Looking at the code (which I took from HEAD yesterday), I can't see any reference to a pcache logging level (servers/slapd/bconfig.c):
It is registered by the overlay itself as soon as it is initialized.
