03858c078b Add positive defense against dropped columns, per suggestion from
Christopher Kings-Lynne.  Also fix a couple more schema-awareness issues.

0b1ee9b5a3 fix hlfinditem function. Thanks to "Stphane Bidoul" <stephane.bidoul@softwareag.com>.
The 'word' variable there is initialised from
the prs->words array, but immediately after,
that array may be reallocated, thus leaving
word pointing to unallocated memory.

3f43446e36 Persuade tsearch/tsearch2 to work (or at least pass their regression
tests) when using flex 2.5.31.  The fix is to *not* try to use palloc
and pfree for allocations within the lexer; when you do that, the
yy_buffer_stack gets freed at inopportune times.  The code is already
set up to do manual deallocation, so I see no particular advantage to
using palloc anyway.

c472b8366f With Joe Conway's concurrence, remove srandom() call from normal_rand().
This was the last piece of code that took it upon itself to reset the
random number sequence --- now we only have srandom() in postmaster start,
backend start, and explicit setseed() operations.

I had to make a further change to this to take quotes off the 'last
ANALYZE' in order for it to not overquote the relation name, so
there's a _little_ work left to get it to play well.

I have deployed it onto several boxes that should be doing some
vacuuming over the weekend, and it is now certainly hitting pg_
tables.

I would like to present a CVS-oriented patch; unfortunately, I had to
change the indentation patterns when editing some of it :-(.  The
following _may_ be good; not sure...

3d48045ae1 > It quotes table names for vacuum and analyze, and uppercases the
> keywords for clarity.

Yeah, this is basically what I meant, sorry I didn't get to it quicker.

However, I tested it out a little and the patch you made doesn't work
because it produces commands like:

VACUUM ANALYZE "public.FooBar"

Which doesn't work, so I made my own patch that creates commands like:

VACUUM ANALYZE "public"."FooBar"

This allows for mixed case schema names as well as tables.

Adam, can you please give this a test as you are the person who caught
the bug in the first place.

Thanks,

33ab177a56 Don't assume that struct option is available just because we can find a
getopt_long().  This is more or less the same problem as we saw earlier
with getaddrinfo() and struct addrinfo, and for the same reason: random
user-added libraries might contain the subroutine, but there's no
guarantee we will find the matching header files.

82bade79dc dbf2pg - Insert xBase-style .dbf-files into a PostgreSQL-table
There is an option "-s oldname=newname", which changes the old field name of
  the dbf-file to the newname in PostgeSQL. If the length of the new name is 0,
  the field is skiped. If you want to skip the first field of the dbf-file,
  you get the wildest error-messages from the backend.
  dbf2pg load the dbf-file via "COPY tablename FROM STDIN". If you skip the
  first field, it is an \t to much in STDIN.

A fix could be an counter j=0, which increments only, if a field is imported
(IF (strlen(fields[h].db_name)> 0) j++. And only if j > 1 (if an other field is
imported) the \t is printed.

An other small bug in the README:
-s start
              Specify  the  first record-number in the xBase-file
              we will insert.
should be
-e start
              Specify  the  first record-number in the xBase-file
              we will insert.

b24a0293cc Attached is a patch that provides *VERY* limited support for multiple
slave
servers.  I haven't tested it very well, so use at your own risk (and I
recommend against using it in production).

Basically, I have a central database server that has 4 summary tables
inside
it replicated to a remote slave (these database tables are for my mail
server
authentication, so these are replicated to another server tuned for many
connections, and so I don't have postgres connections opened straight to
my
back-end database server).

Unfortunately, I also wanted to implement a replication database server
for
hot-backups.  I realized, too late, that the replication process is
pretty
greedy and will try to replicate all tables marked as a
"MasterAddTable".

To make a long story, I made a patch to RServ.pm and Replicate that
allows you
to specify, on the command line, a list of tables that you want to
replicate...it'll ignore all others.

I haven't finished, since this has to be integrated with CleanLog for
instance, but this should (and does) suffice for the moment.

I have yet to test it with two slaves, but at least my mail server
replication
database now works (it was failing every time it tried to replicate, for
a
variety of reasons).

Anyone have any suggestions on how to improve on this?  (or, if someone
more
familiar with this code wants to take the ball and run with it, you're
welcome to).

Nice catch.

There was a bug in the original metaphone algorithm from CPAN. Patch
attached (while I was at it I updated my email address, changed the
copyright to PGDG, and removed an unnecessary palloc). Here's how it
looks now:

regression=# select metaphone(a,4) from (select 'A A COMEAUX
MEMORIAL'::varchar AS a) a;
   metaphone
-----------
   AKMK
(1 row)

regression=# select metaphone(a,5) from (select 'A A COMEAUX
MEMORIAL'::varchar AS a) a;
   metaphone
-----------
   AKMKS
(1 row)

9243664dd4 This patch updates pg_autovacuum in several ways:
* A few bug fixes
* fixes solaris compile and crash issue
* decouple vacuum analyze and analyze thresholds
* detach from tty (dameonize)
* improved logging layout
* more conservative default configuration
* improved, expanded and updated README

please apply and 1st convenience, or before code freeze which ever comes
first :-)

At this point I think I have brought pg_autovacuum and its client side
design as far as I think it should go.  It works, keeping file sizes in
check, helps performance and give the administrator a fair amount
flexibility in configuring it.

Next up is to do the FSM based design that is integrated into the back
end.

p.s. Thanks to Christopher Browne for his help.

fc8d970cbc Replace functional-index facility with expressional indexes. Any column
of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects).  This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up.  Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

f45df8c014 Cause CHAR(n) to TEXT or VARCHAR conversion to automatically strip trailing
blanks, in hopes of reducing the surprise factor for newbies.  Remove
redundant operators for VARCHAR (it depends wholly on TEXT operations now).
Clean up resolution of ambiguous operators/functions to avoid surprising
choices for domains: domains are treated as equivalent to their base types
and binary-coercibility is no longer considered a preference item when
choosing among multiple operators/functions.  IsBinaryCoercible now correctly
reflects the notion that you need *only* relabel the type to get from type
A to type B: that is, a domain is binary-coercible to its base type, but
not vice versa.  Various marginal cleanup, including merging the essentially
duplicate resolution code in parse_func.c and parse_oper.c.  Improve opr_sanity
regression test to understand about binary compatibility (using pg_cast),
and fix a couple of small errors in the catalogs revealed thereby.
Restructure "special operator" handling to fetch operators via index opclasses
rather than hardwiring assumptions about names (cleans up the pattern_ops
stuff a little).

de28dc9a04 Portal and memory management infrastructure for extended query protocol.
Both plannable queries and utility commands are now always executed
within Portals, which have been revamped so that they can handle the
load (they used to be good only for single SELECT queries).  Restructure
code to push command-completion-tag selection logic out of postgres.c,
so that it won't have to be duplicated between simple and extended queries.
initdb forced due to addition of a field to Query nodes.

54f7338fa1 This patch implements holdable cursors, following the proposal
(materialization into a tuple store) discussed on pgsql-hackers earlier.
I've updated the documentation and the regression tests.

Notes on the implementation:

- I needed to change the tuple store API slightly -- it assumes that it
won't be used to hold data across transaction boundaries, so the temp
files that it uses for on-disk storage are automatically reclaimed at
end-of-transaction. I added a flag to tuplestore_begin_heap() to control
this behavior. Is changing the tuple store API in this fashion OK?

- in order to store executor results in a tuple store, I added a new
CommandDest. This works well for the most part, with one exception: the
current DestFunction API doesn't provide enough information to allow the
Executor to store results into an arbitrary tuple store (where the
particular tuple store to use is chosen by the call site of
ExecutorRun). To workaround this, I've temporarily hacked up a solution
that works, but is not ideal: since the receiveTuple DestFunction is
passed the portal name, we can use that to lookup the Portal data
structure for the cursor and then use that to get at the tuple store the
Portal is using. This unnecessarily ties the Portal code with the
tupleReceiver code, but it works...

The proper fix for this is probably to change the DestFunction API --
Tom suggested passing the full QueryDesc to the receiveTuple function.
In that case, callers of ExecutorRun could "subclass" QueryDesc to add
any additional fields that their particular CommandDest needed to get
access to. This approach would work, but I'd like to think about it for
a little bit longer before deciding which route to go. In the mean time,
the code works fine, so I don't think a fix is urgent.

- (semi-related) I added a NO SCROLL keyword to DECLARE CURSOR, and
adjusted the behavior of SCROLL in accordance with the discussion on
-hackers.

- (unrelated) Cleaned up some SGML markup in sql.sgml, copy.sgml

bd18c50ba8 I have updated my pg_autovacuum program (formerly pg_avd, the name
changed as per discussion on the patches list).

This version should be a good bit better.  It addresses all the issues
pointed out by Neil Conway. Vacuum and Analyze are now handled
separately.  It now monitors for xid wraparound.  The number of database
connections and queries has been significantly reduced compared the
previous version.  I have moved it from bin to contrib.  More detail on
the changes are in the TODO file.

I have not tested the xid wraparound code as I have to let my AthlonXP
1600 run select 1 in a tight loop for approx. two days in order to
perform the required 500,000,000 xacts.

64d0b8b05f Attached is an update to contrib/tablefunc. It implements a new hashed
version of crosstab. This fixes a major deficiency in real-world use of
the original version. Easiest to undestand with an illustration:

Data:
-------------------------------------------------------------------
select * from cth;
  id | rowid |        rowdt        |   attribute    |      val
----+-------+---------------------+----------------+---------------
   1 | test1 | 2003-03-01 00:00:00 | temperature    | 42
   2 | test1 | 2003-03-01 00:00:00 | test_result    | PASS
   3 | test1 | 2003-03-01 00:00:00 | volts          | 2.6987
   4 | test2 | 2003-03-02 00:00:00 | temperature    | 53
   5 | test2 | 2003-03-02 00:00:00 | test_result    | FAIL
   6 | test2 | 2003-03-02 00:00:00 | test_startdate | 01 March 2003
   7 | test2 | 2003-03-02 00:00:00 | volts          | 3.1234
(7 rows)

Original crosstab:
-------------------------------------------------------------------
SELECT * FROM crosstab(
   'SELECT rowid, attribute, val FROM cth ORDER BY 1,2',4)
AS c(rowid text, temperature text, test_result text, test_startdate
text, volts text);
  rowid | temperature | test_result | test_startdate | volts
-------+-------------+-------------+----------------+--------
  test1 | 42          | PASS        | 2.6987         |
  test2 | 53          | FAIL        | 01 March 2003  | 3.1234
(2 rows)

Hashed crosstab:
-------------------------------------------------------------------
SELECT * FROM crosstab(
   'SELECT rowid, attribute, val FROM cth ORDER BY 1',
   'SELECT DISTINCT attribute FROM cth ORDER BY 1')
AS c(rowid text, temperature int4, test_result text, test_startdate
timestamp, volts float8);
  rowid | temperature | test_result |   test_startdate    | volts
-------+-------------+-------------+---------------------+--------
  test1 |          42 | PASS        |                     | 2.6987
  test2 |          53 | FAIL        | 2003-03-01 00:00:00 | 3.1234
(2 rows)

Notice that the original crosstab slides data over to the left in the
result tuple when it encounters missing data. In order to work around
this you have to be make your source sql do all sorts of contortions
(cartesian join of distinct rowid with distinct attribute; left join
that back to the real source data). The new version avoids this by
building a hash table using a second distinct attribute query.

The new version also allows for "extra" columns (see the README) and
allows the result columns to be coerced into differing datatypes if they
are suitable (as shown above).

In testing a "real-world" data set (69 distinct rowid's, 27 distinct
categories/attributes, multiple missing data points) I saw about a
5-fold improvement in execution time (from about 2200 ms old, to 440 ms
new).

I left the original version intact because: 1) BC, 2) it is probably
slightly faster if you know that you have no missing attributes.

README and regression test adjustments included. If there are no
objections, please apply.

aa60eecc37 Revise tuplestore and nodeMaterial so that we don't have to read the
entire contents of the subplan into the tuplestore before we can return
any tuples.  Instead, the tuplestore holds what we've already read, and
we fetch additional rows from the subplan as needed.  Random access to
the previously-read rows works with the tuplestore, and doesn't affect
the state of the partially-read subplan.  This is a step towards fixing
the problems with cursors over complex queries --- we don't want to
stick in Materialize nodes if they'll prevent quick startup for a cursor.

9ccaaf676f The attached patches change earthdistance to use the new cube functions
in one of the earth functions so that latitude and longitude to
cartesian coordinates conversion will be more accurrate. (Previously
a text string was built to provide as input which limited the accuracy
to the number of digits printed.)

The new functions were included in a recent patch to contrib/cube that has not
as yet been accepted as of yet.

I also added check constraints to the domain 'earth' since they are now
working in 7.4.

cube(float8,float8) returns cube
cube(cube,float8) returns cube
cube(cube,float8,float8) returns cube

b842726fc7 I've simplified the Darwin/Mac OS X startup script I submitted earlier
in the year. This version has only the two files required by the Darwin
startup bundle design. Plus the sh script now uses Darwin-standard
functions to start up PostgreSQL, and it checks for the presence of a
variable in /etc/hostconfig, as do other Darwin startup scripts.

I suggest that a new directory be created,
contrib/start-scripts/darwin, and that these two files be put into it.
Folks who want to use the script can read the comments inside it to
figure out how to use it.
