53e99f57fc Make an editorial pass over the newly SGML-ified contrib documentation. 
Fix lots of bad markup, bad English, bad explanations.

This commit covers only about half the contrib modules, but I grow weary...

3b3251cb95 Ensure that all <sect1> and <refentry> tags have IDs. This is needed 
to ensure that the resulting webpages have predictable URLs, instead of
ever-changing numeric IDs.  The new contrib docs were the biggest
offender, but some old stuff had the problem too.  Also, rename a couple
of new contrib sgml files for consistency's sake.

07daff63c5 Fix select_common_type() so that it can select a domain type, if all inputs 
to a UNION, CASE, or related construct are of the same domain type.  The
main part of this routine smashes domains to their base types, which seems
necessary because the logic involves TypeCategory() and IsPreferredType(),
neither of which work usefully on domains.  However, we can add a first
pass that just detects whether all the inputs are exactly the same type,
and if so accept that without question (so long as it's not UNKNOWN).
Per recent gripe from Dean Rasheed.

In passing, remove some tests for InvalidOid, which have clearly been dead
code for quite some time now, because getBaseType() would fail on that input.

Also, clarify the manual's not-very-precise description of the existing
algorithm's behavior.

866bad9543 Add a rank/(rank+1) normalization option to ts_rank(). While the usefulness 
of this seems a bit marginal, if it's useful enough to be shown in the manual

ts_rank function.  Per my proposal earlier today.

ca450a07ee Add an Accept parameter to "simple" dictionaries. The default of true 
gives the old behavior; selecting false allows the dictionary to be used

048efc25e4 Disallow scrolling of FOR UPDATE/FOR SHARE cursors, so as to avoid problems 
in corner cases such as re-fetching a just-deleted row.  We may be able to

we invest a lot of work in it.  Per report from Heikki and subsequent
discussion.

While in the neighborhood, make the combination of INSENSITIVE and FOR UPDATE
throw an error, since they are semantically incompatible.  (Up to now we've
accepted but just ignored the INSENSITIVE option of DECLARE CURSOR.)

592c88a0d2 Remove the aggregate form of ts_rewrite(), since it doesn't work as desired 
if there are zero rows to aggregate over, and the API seems both conceptually

on the tsquery-and-text-SELECT version (which is also pretty ugly but at
least it works...), but it seems that will take query infrastructure that
doesn't exist today.  (Hm, I wonder if there's anything in or near SQL2003
window functions that would help?)  Per discussion.

dbaec70c15 Rename and slightly redefine the default text search parser's "word" 
categories, as per discussion.  asciiword (formerly lword) is still
ASCII-letters-only, and numword (formerly word) is still the most general
mixed-alpha-and-digits case.  But word (formerly nlword) is now
any-group-of-letters-with-at-least-one-non-ASCII, rather than all-non-ASCII as
before.  This is no worse than before for parsing mixed Russian/English text,
which seems to have been the design center for the original coding; and it
should simplify matters for parsing most European languages.  In particular
it will not be necessary for any language to accept strings containing digits
as being regular "words".  The hyphenated-word categories are adjusted
similarly.

composite type, to be consistent with the other built-in functions.

painted ourselves into a corner if we want to support multiple types of TOAST
pointer later on.  Per discussion with Greg Stark.

b46bd55a6c Make archive recovery always start a new timeline, rather than only when a 
recovery stop time was used.  This avoids a corner-case risk of trying to
overwrite an existing archived copy of the last WAL segment, and seems
simpler and cleaner all around than the original definition.  Per example
from Jon Colverson and subsequent analysis by Simon.

70b9b9b788 Change initdb and CREATE DATABASE to actively reject attempts to create 
databases with encodings that are incompatible with the server's LC_CTYPE
locale, when we can determine that (which we can on most modern platforms,
I believe).  C/POSIX locale is compatible with all encodings, of course,
so there is still some usefulness to CREATE DATABASE's ENCODING option,
but this will insulate us against all sorts of recurring complaints
caused by mismatched settings.

I moved initdb's existing LC_CTYPE-to-encoding mapping knowledge into
a new src/port/ file so it could be shared by CREATE DATABASE.

6f5c38dcd0 Just-in-time background writing strategy. This code avoids re-scanning 
buffers that cannot possibly need to be cleaned, and estimates how many
buffers it should try to clean based on moving averages of recent allocation
requests and density of reusable buffers.  The patch also adds a couple
more columns to pg_stat_bgwriter to help measure the effectiveness of the
bgwriter.

Greg Smith, building on his own work and ideas from several other people,
in particular a much older patch from Itagaki Takahiro.

48f7e64395 Simplify and rename some GUC variables, per various recent discussions: 
* stats_start_collector goes away; we always start the collector process,
unless prevented by a problem with setting up the stats UDP socket.

* stats_reset_on_server_start goes away; it seems useless in view of the
availability of pg_stat_reset().

* stats_block_level and stats_row_level are merged into a single variable
"track_counts", which controls all reports sent to the collector process.

* stats_command_string is renamed to track_activities.

* log_autovacuum is renamed to log_autovacuum_min_duration to better reflect
its meaning.

The log_autovacuum change is not a compatibility issue since it didn't exist
before 8.3 anyway.  The other changes need to be release-noted.

cc59049daf Improve handling of prune/no-prune decisions by storing a page's oldest 
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.

282d2a03dd HOT updates. When we update a tuple without changing any of its indexed 
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.

55613bf9cd Close previously open holes for invalidly encoded data to enter the 
database via builtin functions, as recently discussed on -hackers.

chr() now returns a character in the database encoding. For UTF8 encoded databases
the argument is treated as a Unicode code point. For other multi-byte encodings
the argument must designate a strict ascii character, or an error is raised,
as is also the case if the argument is 0.

ascii() is adjusted so that it remains the inverse of chr().

The two argument form of convert() is gone, and the three argument form now
takes a bytea first argument and returns a bytea. To cover this loss three new
functions are introduced:
. convert_from(bytea, name) returns text - converts the first argument from the
  named encoding to the database encoding
. convert_to(text, name) returns bytea - converts the first argument from the
  database encoding to the named encoding
. length(bytea, name) returns int - gives the length of the first argument in
  characters in the named encoding

82a47982f3 Arrange for SET LOCAL's effects to persist until the end of the current top 
transaction, unless rolled back or overridden by a SET clause for the same
variable attached to a surrounding function call.  Per discussion, these
seem the best semantics.  Note that this is an INCOMPATIBLE CHANGE: in 8.0
through 8.2, SET LOCAL's effects disappeared at subtransaction commit
(leading to behavior that made little sense at the SQL level).

I took advantage of the opportunity to rewrite and simplify the GUC variable
save/restore logic a little bit.  The old idea of a "tentative" value is gone;
it was a hangover from before we had a stack.  Also, we no longer need a stack
entry for every nesting level, but only for those in which a variable's value
actually changed.

295e63983d Implement lazy XID allocation: transactions that do not modify any database 
rows will normally never obtain an XID at all.  We already did things this way
for subtransactions, but this patch extends the concept to top-level
transactions.  In applications where there are lots of short read-only
transactions, this should improve performance noticeably; not so much from
removal of the actual XID-assignments, as from reduction of overhead that's
driven by the rate of XID consumption.  We add a concept of a "virtual
transaction ID" so that active transactions can be uniquely identified even
if they don't have a regular XID.  This is a much lighter-weight concept:
uniqueness of VXIDs is only guaranteed over the short term, and no on-disk
record is made about them.
