Sooooo... Back to this.
It won't happen unless somebody does it - and I realize that people
are busy with their own projects, so unless somebody more willing and
better suited will step up, I'm going to take a stab at getting
advanced consensus.
Please answer the below questions, and state whether your opinion is
just an opinion, or whether you are stating it as a PostgreSQL
maintainer and it is law. If you wish, you can rank preferences.
1) The added 128-bit type should take the form of:
a) UUID, with all functions
b) UUID, with only basic generation functions + encode/decode/indexable
c) UUID, with only encode/decode/indexable - generic except for the
name of the type, and the encoding format.
d) Generic 128-bit type - same as c) except may not encode or decode
as UUID (dashes). Either a large number (hex string?), or binary data.
e) Generic n-byte binary data type generator. Not sure of feasibility
of this at this point. See thread.
2) According to your answer in 1), the added 128-bit type should be:
a) In core first.
b) In contrib first.
c) In pgfoundry first.
Thanks,
mark
