You probably want to enable debug output in resource agent. As far as I
can tell, this requires HA_debug=1 in environment of resource agent, but
for the life of me I cannot find where it is possible to set it.

Probably setting it directly in resource agent for debugging is the most
simple way.

P.S. crm_resource is called by resource agent (pgsqlms). And it shows
result of original resource probing which makes it confusing. At least
it explains where these logs entries come from.
