the first paragraph:
As an example, say we wish to find all the records that
are in the temperature range of other records. In
effect, we need to compare the temp_lo and temp_hi
attributes of each EMP instance to the temp_lo and
temp_hi attributes of all other EMP instances.
I believe that EMP should read WEATHER, as the example query that
follows joins WEATHER to itself.
EMP is often used in Oracle examples.

Other RULE cleanups
ISO-compliant UNION/INTERSECT/EXCEPT. Revise discussion of rule
rewriter to reflect new subselect-in-FROM implementation of views.
Miscellaneous other cleanups.
line 1324:
"left-hand" should be "right-hand"
BTW: new document looks very good!
And the new configure/build process seems much better then before!
Thanks!

value greater than one. The behavior this sought to disallow doesn't
seem any less confusing than the other behaviors of cached sequences.
Improve wording of some error messages, too.
Update documentation accordingly. Also add an explanation that
aborted transactions do not roll back their nextval() calls; this
seems to be a FAQ, so it ought to be mentioned here...
IPC key assignment will now work correctly even when multiple postmasters
are using same logical port number (which is possible given -k switch).
There is only one shared-mem segment per postmaster now, not 3.
Rip out broken code for non-TAS case in bufmgr and xlog, substitute a
complete S_LOCK emulation using semaphores in spin.c. TAS and non-TAS
logic is now exactly the same.
When deadlock is detected, "Deadlock detected" is now the elog(ERROR)
message, rather than a NOTICE that comes out before an unhelpful ERROR.
re-adopt these settings at every postmaster or standalone-backend startup.
This should fix problems with indexes becoming corrupt due to failure to
provide consistent locale environment for postmaster at all times. Also,
refuse to start up a non-locale-enabled compilation in a database originally
initdb'd with a non-C locale. Suppress LIKE index optimization if locale
is not "C" or "POSIX" (are there any other locales where it's safe?).
Issue NOTICE during initdb if selected locale disables LIKE optimization.
it fixing Y,YY,YYY,YYYY conversion, the docs and regress tests update
are included too.
During the patch testing I found small bug in miscadmin.h in
convertstr() declaration. Here it's fixed too.
Thanks

Make version.sgml the central place for updating version numbers in the
documentation. Document titles now contain the version number of the
release they belong to.
filelist.sgml is the central (and only) place to declare system entities
(i.e., sgml files). No longer a need to declare them in each document
header.
There is no longer any need to maintain duplicate chapter lists in
postgres.sgml and user/admin/etc.sgml, everything is build from the same
sources. Some parameter entities allow for different text to be included
when the integrated or a single doc set is generated, which eliminates the
problems that had caused this to fail in the past.
in pghackers list. Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention. pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'. A newstyle function must be identified
by an associated info routine. See src/backend/utils/fmgr/README.
maintained for each cache entry. A cache entry will not be freed until
the matching ReleaseSysCache call has been executed. This eliminates
worries about cache entries getting dropped while still in use. See
my posting to pg-hackers of even date for more info.
