2015-11-06Remove unnecessary cast in previous commit.Robert Haas
Noted by Kyotaro Horiguchi, who also reviewed the previous patch, but I failed to notice his review before committing.
2015-11-06Add sort support routine for the UUID data type.Robert Haas
This introduces a simple encoding scheme to produce abbreviated keys: pack as many bytes of each UUID as will fit into a Datum. On little-endian machines, a byteswap is also performed; the abbreviated comparator can therefore just consist of a simple 3-way unsigned integer comparison. The purpose of this change is to speed up sorting data on a column of type UUID. Peter Geoghegan

2008-11-03Use bool for a boolean flag.Tom Lane
2008-11-03Allow uuid_in() to parse a wider variety of variant input formats for the UUIDPeter Eisentraut
data type. This patch takes the approach of allowing an optional hyphen after each group of four hex digits. Author: Robert Haas <robertmhaas@gmail.com>

2007-11-15Re-run pgindent with updated list of typedefs. (Updated README shouldBruce Momjian
avoid this problem in the future.)

2007-06-05Downgrade implicit casts to text to be assignment-only, except for the onesTom Lane
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
2007-01-31Rewrite uuid input and output routines to avoid dependency on theNeil Conway
nonportable "hh" sprintf(3) length modifier. Instead, do the parsing and output by hand. The code to do this isn't ideal, but this is an interim measure anyway: the uuid type should probably use the in-memory struct layout specified by RFC 4122. For now, this patch should hopefully rectify the buildfarm failures for the uuid test. Along the way, re-add pg_cast entries for uuid <-> varchar, which I mistakenly removed earlier, and bump the catversion.
2007-01-28Rename the uuid_t type to pg_uuid_t, to avoid a conflict with anyNeil Conway
definitions of uuid_t that may be provided by the system headers. This should hopefully fix the Win32 build problems reported by Magnus.
2007-01-28Add a new builtin type, "uuid". This implements a UUID type, similar toNeil Conway
that defined in RFC 4122. This patch includes the basic implementation, plus regression tests. Documentation and perhaps some additional functionality will come later. Catversion bumped. Patch from Gevik Babakhani; review from Peter, Tom, and myself.
