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. Peter Eisentraut and Tom Lane	19 years ago

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.

Tom Lane	dcf2e1c8c7	Remove the << >> &< and &> operators for contrib/cube, which were ... wrong, but nobody noticed because they were also useless.	21 years ago
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 Bruno Wolff III	23 years ago
Bruce Momjian	e5cf1a8a26	SET autocommit no longer needed in /contrib because pg_regress.sh does ... it automatically now on regression session startup.	23 years ago
Bruce Momjian	aa4c702eac	Update /contrib for "autocommit TO 'on'". ... Create objects in public schema. Make spacing/capitalization consistent. Remove transaction block use for object creation. Remove unneeded function GRANTs.	23 years ago
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. Bruno Wolff III	23 years ago
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. Bruno Wolff III	23 years ago
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.	24 years ago
