Current CLOBBER_CACHE_ALWAYS failures - Mailing list pgsql-hackers

The CLOBBER_CACHE_ALWAYS animals (friarbird and jaguarundi) have been 
failing persistently for about 36 hours now. The error is in a test 
added by Tom's recent commit a4424c5:

Expected:

-- Check row comparisons with IN
select * from int8_tbl i8 where i8 in (row(123,456));  -- fail, type 
mismatch
ERROR:  cannot compare dissimilar column types bigint and integer at 
record column 1

Actual:

select * from int8_tbl i8 where i8 in (row(123,456));  -- fail, type 
mismatch
connection to server was lost

Backtrace, as good as I can make it:
