Bruce Momjian	04a4821ade	Attached is a patch implementing factorial(), returning numeric. Points to note: 1) arttype is numeric. I thought this was the best way of allowing arbitarily large factorials, even though factorial(2^63) is a large number. Happy to change to integers if this is overkill. 2) since we're accepting numeric arguments, the patch tests for floats. If a numeric is passed with non-zero decimal portion, an error is raised since (from memory) they are undefined. Gavin Sherry	22 years ago
Tom Lane	42ce74bf17	COMMENT ON casts, conversions, languages, operator classes, and large objects. Dump all these in pg_dump; also add code to pg_dump user-defined conversions. Make psql's large object code rely on the backend for inserting/deleting LOB comments, instead of trying to hack pg_description directly. Documentation and regression tests added.

Marc G. Fournier	9e2a87b62d	Major patch from Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> OK, here are a passel of patches for the geometric data types. These add a "circle" data type, new operators and functions for the existing data types, and change the default formats for some of the existing types to make them consistant with each other. Current formatting conventions (e.g. compatible with v6.0 to allow dump/reload) are supported, but the new conventions should be an improvement and we can eventually drop the old conventions entirely. For example, there are two kinds of paths (connected line segments), open and closed, and the old format was '(1,2,1,2,3,4)' for a closed path with two points (1,2) and (3,4) '(0,2,1,2,3,4)' for an open path with two points (1,2) and (3,4) Pretty arcane, huh? The new format for paths is '((1,2),(3,4))' for a closed path with two points (1,2) and (3,4) '[(1,2),(3,4)]' for an open path with two points (1,2) and (3,4) For polygons, the old convention is '(0,4,2,0,4,3)' for a triangle with points at (0,0),(4,4), and (2,3) and the new convention is '((0,0),(4,4),(2,3))' for a triangle with points at (0,0),(4,4), and (2,3) Other data types which are also represented as lists of points (e.g. boxes, line segments, and polygons) have similar representations (they surround each point with parens). For v6.1, any format which can be interpreted as the old style format is decoded as such; we can remove that backwards compatibility but ugly convention for v7.0. This will allow dump/reloads from v6.0. These include some updates to the regression test files to change the test for creating a data type from "circle" to "widget" to keep the test from trashing the new builtin circle type.	29 years ago
