Yes, significantly. Times to hash 32K bytes 10 times on a Xeon EM64T:
hash_crc(32K): 11.388755 s
hash_any_old(32K): 4.401945 s

So the proposed changes in hash_any make its hash values different
between big-endian and little-endian machines (at least for string keys;
for keys that are really arrays of int, I think the changes will
unify the behavior). This means that the hash_seq_search traversal

In 8.3, autovacuum cancels itself if it sees it is conflicting with
another query.
Would this be the issue fixed

In 8.3, autovacuum cancels itself if it sees it is conflicting with

I am currently attempting to import the world street map data as
currently available from openstreetmap.org and am wondering if I will
come across a possible problem that is mentioned on their website, which
appears to be relevant for 8.1

Well maybe you don't want *every* customer to have it or not every customer
