BTW, these scripts seem to indicate that there's a GIST or
contrib/intarray problem in the 8.0 branch.  I was trying to use 'em
to test REL8_0_STABLE branch tip to verify my t_ctid chain backpatch,
and I pretty consistently see "Problem with update":

Start: parallel mode with 4 flows
Problem with update {77,77}:0 count:1 at concur.pl line 91.
Issuing rollback() for database handle being DESTROY'd without explicit disconnect().
Problem with update {43,24}:3 count:1 at concur.pl line 91.

1 flow finish. Stats: ni:75000 nu:1661 nd:216 nv:13(nf:3) nt:780
All flow finish; status: 255; elapsed time: 265.48 sec

Is this something that can be fixed for 8.0.4?
