data. This makes for a significant speedup at the cost that the results
now vary between little-endian and big-endian machines; which forces us
to add explicit ORDER BYs in a couple of regression tests to preserve
machine-independent comparison results. Also, force initdb by bumping
catversion, since the contents of hash indexes will change (at least on
big-endian machines).

does not adopt Bob's new faster mix() algorithm, however, since we still need
to convince ourselves that that doesn't degrade the quality of the hashing.
failed to cover all the ways in which a connection can be initiated in dblink.
Plug the remaining holes. Also, disallow transient connections in functions
for which that feature makes no sense (because they are only sensible as
part of a sequence of operations on the same connection). Joe Conway

that you should suppress NOTICE messages. This avoids creating
regression failures by adding or removing comment lines in the module
scripts.

the open transaction if it was started by dblink_open, and only
then when all cursors opened by dblink_open are closed. The transaction
accounting is done individually for all named connections, plus
the persistent unnamed connection.

The test creates a second database (regression_slave) and drops it again, in
order to avoid the cheesy-ness of connecting back to the same database ;-)
