Buildfarm critters friarbird and jaguarundi have been failing for 11
days, apparently due to the sql_drop event for event triggers feature.
These are both FBSD machines, but more importantly are both building
with -DCLOBBER_CACHE_ALWAYS.
Tom complained about it at the time, see
<http://www.postgresql.org/message-id/6676.1364599344@sss.pgh.pa.us> ,
but I don't recall seeing a response to his complaint.
cheers
