How difficult can be creating an hypertable in TimescaleDB?
It seems that pretty much of a fucking lot.

If there's some way to manually edit the starting values for the auto-incrementing IDs that would be cool too.
What is the best way to backup/export a Postgres DB with auto-incrementing ids and restore it without causing IDs to overlap when new items are added?
A plain SQL dump is a no-go because the IDs get reset to 1, which causes the above issue.
A SQL dump omitting the IDs and allowing the DB to generate new IDs on insert is also not ideal because it will fuck up the many various relations.
It seems like there are myths around relational databases that contribute to the idea that they are slow. I saw one person just now who thought that a basic transaction reading from a table would lock the entire table and block everything else from accessing the table.
Relational databases are more efficient than that! Transactions can be isolated without blocking.
What Inka Quipus teach us about data management
* Lesson 1: Without #metadata, your records will not make it into history
* Lesson 2: Human readable encoding is advantageous
* Lesson 3: A document store is more flexible than a classic #relationaldatabase
* Lesson 4: There is ancient logic to append-only databases

What Inka quipus teach us about data management Chances are that your knowledge of ancient Peruvian culture is a bit rusty. Maybe you have some vague high-school memories of an extensive but backward empire that was conquered and then asset-stripped by a handful of Spanish conquistadores. Or maybe your best preserved memory is the excitement of reading von Daniken’s speculations that the Nazca lines are extraterrestrial spaceports. But unless you happened at some point later in life to hear about the work of Prof.

...spent way too long trying to get a table join to work thinking it was a formatting issue, then remembered that the area had recently been redistricted. Works like a charm, now! 😭 😂
