Many big Postgres databases today use partitioning. Do you have a default partition? If not, you probably should. Default partitions are super important because they let you catch inconsistent data or bugs in your application code.

Postgres Partitioning with a Default Partition | Crunchy Data Blog
Keith discusses the importance of having a default partition, how to monitor the default, and how to move rows to new child tables.

You can make auto-incrementing columns in Oracle Database with either

<col> GENERATED ... AS IDENTITY
<col> DEFAULT ... <sequence>.NEXTVAL

Using the DEFAULT ON NULL clause for these, the database will populate the columns if you insert

DEFAULT
NULL
Omit the column

Example: For this
WHERE EXTRACT(YEAR FROM ts_col) = 2024

Someone might come up with that index:
CREATE INDEX … ON … (EXTRACT(YEAR FROM ts_col))
