What needs to be stored as text if there is a native uuid type?

Chapter 8. Data Types > Table 8.2. Numeric Types: https://www.postgresql.org/docs/current/datatype-numeric.htm... :

> bigint: -9223372036854775808 to +9223372036854775807

> bigserial: 1 to 9223372036854775807

2*63 == 9223372036854775807

Todo UUID /? postgres bigint UUID: https://www.google.com/search?q=postgres+bigint+uuid :

- UUIDs are 128 bits, and they're unsigned, so: 2*127

FWIW networkx has an in-memory Graph.relabel_nodes() method that assigns ints to unique node names in order to reduce RAM utilization for graph algorithms: https://networkx.org/documentation/stable/reference/generate...

Many people store UUID's as text in the database. Needles to say, this is bad. TFA starts by proposing that it's bad, then does some tests to show why.

I'm not quite sure what all the links have to do with the topic at hand.

Which link are you concerned about the topicality of, in specific?

Shouldn't we then link to the docs on how many bits wide db datatypes are, whether a datatype is prefix or suffix searchable, whether there's data leakage in UUID namespacing with primary NIC MAC address and UUIDv7, and whether there will be overflow with a datatype less wasteful than the text datatype for uuids when there is already a UUID datatype for uuids that one could argue to improve if there is a potential performance benefit
