pika buildfarm member failure on isolationCheck tests

Hi,

Pika failed at the isolationCheck phase, hitting an assertion:

TRAP: FailedAssertion("!(!((oldSerXidControl->tailXid) != ((TransactionId) 0)) || TransactionIdFollows(xid,
oldSerXidControl->tailXid))",File: "predicate.c", Line: 991) 

see http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=pika&dt=2011-06-17%2015%3A45%3A30

It seems that for this stage, the server log (which contains the failed assertion) is not sent back to the buildfarm
server.Maybe that should be fixed ? 

Regards,
