compatibility package. This supports importing dumps from past versions
using tsearch2, and provides the old names and API for most functions
that were changed. (rewrite(ARRAY[...]) is a glaring omission, though.)

about best practice for including the module creation scripts: to wit
that you should suppress NOTICE messages. This avoids creating
regression failures by adding or removing comment lines in the module
scripts.
Remove setting of search_path in install/uninstall scripts, since unlike
other contrib modules this one does not want to let you change the
installation schema.
itself as libuuid, not libossp-uuid which was the only case expected by
our build support. Install a configure test to determine which name
to use (and to check that the library is present at all).
remove transactions
use create or replace function
make formatting consistent
set search patch on first line
Add documentation on modifying *.sql to set the search patch, and
mention that major upgrades should still run the installation scripts.
Some of these issues were spotted by Tom today.

This module offers transaction ID's containing the original XID and the
transaction epoch as a bigint value to the user level. It also provides
a special txid_snapshot data type that contains an entire transactions
visibility snapshot information, which is useful to determine if a
particular txid was visible to a transaction or not.
The module has been tested by porting Slony-I from using its original
xxid data type.

testing). Combine the formerly independent opclasses for the various
ISN types into opfamilies. The latter causes some extra bleating from
opr_sanity, since the module doesn't provide complete sets of cross-type
operators, but it's still a good idea because it will give the planner
more information to work with. The missing cross-type operators no longer
pose a risk of unexpected planner errors in 8.3, so there's no need to
insist on filling them in (and I gather it wouldn't be very sound
semantically to add them all).
couldn't possibly HAVE_GETOPT. I believe this is the most appropriate
form of the patch submitted 2007-08-07 by Hiroshi Saito, though not
having a Windows build environment I won't know for sure till I see
the buildfarm results.
- create a separate archive_mode GUC, on which archive_command is dependent
- %r option in recovery.conf sends last restartpoint to recovery command
- %r used in pg_standby, updated README
- minor other code cleanup in pg_standby
- doc on Warm Standby now mentions pg_standby and %r
- log_restartpoints recovery option emits LOG message at each restartpoint
- end of recovery now displays last transaction end time, as requested
by Warren Little; also shown at each restartpoint
- restart archiver if needed to carry away WAL files at shutdown

unpruned XMAX in its header. At the cost of 4 bytes per page, this keeps us
from performing heap_page_prune when there's no chance of pruning anything.
Seems to be necessary per Heikki's preliminary performance testing.
columns, and the new version can be stored on the same heap page, we no longer
generate extra index entries for the new version. Instead, index searches
follow the HOT-chain links to ensure they find the correct tuple version.
In addition, this patch introduces the ability to "prune" dead tuples on a
per-page basis, without having to do a complete VACUUM pass to recover space.
VACUUM is still needed to clean up dead index entries, however.

than two independent bits (one of which was never used in heap pages anyway,
or at least hadn't been in a very long time). This gives us flexibility to
add the HOT notions of redirected and dead item pointers without requiring
anything so klugy as magic values of lp_off and lp_len. The state values
are chosen so that for the states currently in use (pre-HOT) there is no
change in the physical representation.
