Dear Nikita,
Thanks for reading my patch!
>
I have reviewed the patch in this topic and have a question mentioning the
machine ID -
INSERT INTO snowflake_sequence.machine_id
SELECT round((random() * (0 - 511))::numeric, 0) + 511;
This kind of ID generation does not seem to guarantee from not having the same
ID in a pool
of instances, does it?

You are right. For now the part is randomly assigned, but it might be
duplicated on another instance.
Maybe we should provide a way for setting it manually. Or, we may able to use
another way
for determining machine ID.
(system_identifier is too long to use here...)
Note that the contrib module was provided just for the reference. We are now
discussing high-level items, like needs, use-cases and approaches. Could you
please your opinion around here if you have?
The implementation may be completely changed, so I did not change yet. Of
course,
your comment is quite helpful so that it will be handled eventually.
