Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I set up a three-node cluster where node C acts as a secondary for both
nodes A and B for different resources. Node A & C own resource R1 while
nodes B & C own resource R2. If either node A or node B go down, node C
takes over primary for the failed node while continuing as secondary for
the non-failed node. Since I was able to get this to work, I assume it
is a legal and supported configuration, but it now occurs to me
belatedly to ask if  this is true. Are there caveats I should be
especially concerned about in this configuration?
