Sep 20, 2012 · Postgres natively supports UUID as a data type, even capable of being indexed and used as primary key. But to generate a UUID value, such as to establish a default value for a column, you need a Postgres extension (a plugin). Many builds (distributions) of Postgres include such an extension but do not activate the extension. See the correct answer by Craig Ringer …

Version 4 is the random number UUID. There's six fixed bits and the rest of the UUID is 122-bits of randomness. See Wikipedia or other analysis that describe how very unlikely a duplicate is. Version 3 is uses MD5 and Version 5 uses SHA-1 to create those 122-bits, instead of a random or pseudo-random number generator.

May 21, 2012 · A UUID can be used for multiple purposes, from tagging objects with an extremely short lifetime, to reliably identifying very persistent objects across a network. The internal representation of a UUID is a specific sequence of bits in memory, as described in Section 4. To accurately represent a UUID as a URN, it is necessary to convert the bit
