Tom Lane 81ee726d87 Code and docs review for cube kNN support.
Commit 33bd250f6c could have done with
some more review:

Adjust coding so that compilers unfamiliar with elog/ereport don't complain
about uninitialized values.

Fix misuse of PG_GETARG_INT16 to retrieve arguments declared as "integer"
at the SQL level.  (This was evidently copied from cube_ll_coord and
cube_ur_coord, but those were wrong too.)

Fix non-style-guide-conforming error messages.

Fix underparenthesized if statements, which pgindent would have made a
hash of, and remove some unnecessary parens elsewhere.

Run pgindent over new code.

Revise documentation: repeated accretion of more operators without any
rethinking of the text already there had left things in a bit of a mess.
Merge all the cube operators into one table and adjust surrounding text
appropriately.

Teodor Sigaev 33bd250f6c Cube extension kNN support
Introduce distance operators over cubes:
<#> taxicab distance
<->  euclidean distance
<=> chebyshev distance

Also add kNN support of those distances in GiST opclass.

Heikki Linnakangas 36f4c7843c Adjust cube.out expected output for new test queries.
Previous commit modified the test case, but I didn't update cube.out
expected output file in previous commit because it was not needed by the
platforms I have easy access to. Buildfarm animal 'dugong', running
"Debian 4.0 icc 10.1.011 ia64", has now gone red because of that, so update
it now.

Also adjust cube_3.out. According to git history, it was added to support
64-bit MinGW. There is no such animal in the buildfarm, so I'm doing this
blindly, but it was added quite recently so maybe someone still cares.

Heikki Linnakangas 08612f45a0 Extend cube on-disk format to pack points more tightly.
If the lower left and upper right corners of a cube are the same, set a
flag in the cube header, and only store one copy of the coordinates. That
cuts the on-disk size into half for the common case that the cube datatype
is used to represent points rather than boxes.

The new format is backwards-compatible with the old one, so pg_upgrade
still works. However, to get the space savings, the data needs to be
rewritten. A simple VACUUM FULL or REINDEX is not enough, as the old
Datums will just be moved to the new heap/index as is. A pg_dump and
reload, or something similar like casting to text and back, will do the
trick.

This patch deliberately doesn't update all the alternative expected output
files, as I don't have access to machines that produce those outputs. I'm
not sure if they are still relevant, but if they are, the buildfarm will
tell us and produce the diff required to fix it. If none of the buildfarm
animals need them, they should be removed altogether.

Patch by Stas Kelvich.

Tom Lane 629b3af27d Convert contrib modules to use the extension facility.
This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK.  But it's time to get some
buildfarm cycles on it.

sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

Tom Lane b153c09209 Add a bunch of new error location reports to parse-analysis error messages.
There are still some weak spots around JOIN USING and relation alias lists,
but most errors reported within backend/parser/ now have locations.

Tom Lane 31edbadf4a Downgrade implicit casts to text to be assignment-only, except for the ones
from the other string-category types; this eliminates a lot of surprising
interpretations that the parser could formerly make when there was no directly
applicable operator.

Create a general mechanism that supports casts to and from the standard string
types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's
I/O functions.  These new casts are assignment-only in the to-string direction,
explicit-only in the other, and therefore should create no surprising behavior.
Remove a bunch of thereby-obsoleted datatype-specific casting functions.

The "general mechanism" is a new expression node type CoerceViaIO that can
actually convert between *any* two datatypes if their external text
representations are compatible.  This is more general than needed for the
immediate feature, but might be useful in plpgsql or other places in future.

This commit does nothing about the issue that applying the concatenation
operator || to non-text types will now fail, often with strange error messages
due to misinterpreting the operator as array concatenation.  Since it often
(not always) worked before, we should either make it succeed or at least give
a more user-friendly error; but details are still under debate.

Bruce Momjian 796de9c1ed /contrib/cube improvements:
Update the calling convention for all external facing functions. By
external facing, I mean all functions that are directly referenced in
cube.sql. Prior to my update, all functions used the older V0 calling
convention. They now use V1.

New Functions:

cube(float[]), which makes a zero volume cube from a float array

cube(float[], float[]), which allows the user to create a cube from
two float arrays; one for the upper right and one for the lower left
coordinate.

cube_subset(cube, int4[]), to allow you to reorder or choose a subset of
dimensions from a cube, using index values specified in the array.

Neil Conway 305fcb7aa4 Woops: also update the alternative "expected" files for contrib/cube's
regression tests to account for the new error message wording. It seems
today is not my day...

Neil Conway 485541a3aa Update the expected regression test results to account for the changes to

this, and my apologies for missing it the first time.

Tom Lane 03e47392e0 Make contrib/cube work with flex 2.5.31. Fix it up to have a real
btree operator class, too, since in PG 7.4 you can't GROUP without one.

Tom Lane f85f43dfb5 Backend support for autocommit removed, per recent discussions. The
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

Bruce Momjian 80b3513d57 The attached patch provides cube with 4 functions for building cubes
directly from float8 values. (As opposed to converting the values to
strings
and then parsing the strings.)
The functions are:
cube(float8) returns cube
cube(float8,float8) returns cube
cube(cube,float8) returns cube
cube(cube,float8,float8) returns cube

Bruce Momjian 4987ca2d88 This is a patch to make cube output work like double precision output
with regard to the extra_float_digits setting.

Since builtins.h was already included, I just deleted the extern
statement (and accompaning comments).

Remove unneeded function GRANTs.

Tom Lane fce573ae16 I haven't seen any objections, so here is a patch. It removes "#define
YYERROR_VERBOSE" from contrib/cube and contrib/seg, and adjusts the expected
output accordingly. Hopefully this will consistently pass across multiple
bison versions.

Bruce Momjian e57ab04565 This is a comprehensive set of diffs (versus current CVS) that replaces those
attached to the same message with the Earth Distance patches.
Recent changes include changing the subscript in one place I forgot
in the previous bugfix patch. A couple of added regression tests, which
should help catch this mistake if it reappears.
I also put in a limit of 100 dimensions in cube_large and cube_in to
prevent making it easy to create very large cubes. Changing one define
in cubedata.h will raise the limit if some needs more dimensions.

Bruce Momjian 32784cddf1 The changes I have made are described in CHANGES. This was based on
diffs to 7.3-devel and may not be applicable to 7.2. I have included a
change covered by a previous bugfix patch I submitted (the problem with
-.1 not being accepted by cube_in). It does not include a fix for the
potential buffer overrun issue I reported for cube_yyerror in
cubeparse.y.

Tom Lane 119fd7956a Remove test of 'inf' since it introduces a platform dependency (some
Unixen spell it 'Inf').  Not worth adding multiple expected files and
a resultmap just for this.
