Subject: int_aggregate's int_enum() doesn't work correctly with arrays that
X-Git-Url: http://waps.l3s.uni-hannover.de/gitweb/?a=commitdiff_plain;h=1cb00f0e9b6eb988892d75f9d2238db3c25180c1;p=users%2Fbernd%2Fpostgres.git

int_aggregate's int_enum() doesn't work correctly with arrays that
aren't 1-D, so give an error message instead of failing.  Per report
from Ron Mayer.
