Hi,

Peter Smith has recently reported a BF failure [1]. AFAICS, the call
stack of failure [2] is as follows:

0x1e66644 <ExceptionalCondition+0x8c> at postgres
0x1d0143c <pgstat_release_entry_ref+0x4c0> at postgres
0x1d02534 <pgstat_get_entry_ref+0x780> at postgres

I couldn't correlate it to the recent commits. Any thoughts?
