Cockroach's SERIAL type is currently 64 bits. With the new added SEQUENCE functionality it is possible to implement SERIAL as a postgres compatible 32 bit type.

#18688

This might involve setting the current SERIAL type to a supported backwards compatibility type and introducing another type under the hood for new instances of the type. Caching functionality needs to be implemented for performance.

pg has separate serial and bigserial types. They correspond to int/int4 (32-bit) and bigint/int8 (64 bit) integer types. CockroachDB should arguably do the same.

28575: sql: introduce virtual sequences and use with SERIAL r=knz a=knz

Very good idea by @BramGruneir 

New features: virtual sequences (opt-in) and create-sequence-upon-SERIAL (opt-in). See individual commits for details and release notes.

For reference:

- I made everything opt-in here (i.e. default to previous CockroachDB behavior) to minimize risk.
- UX with Hibernate will thus not automatically be improved. We need to inform users (and upgrade our tutorials/docs) that this experimental feature is available and how to use it to unblock problems.
- It is possible that making the new default be `virtual_sequence` will both be backward-compatible with performance and unlock UX for Hibernate users. This has @awoods187 preference I think. However I propose to only flip that switch after we've seen a week or two pass with this patch merged.

Fixes #22607 (using the new setting set to `sql_sequence`).
Fixes #24062 (using the new setting set to `sql_sequence`).
Fixes #26730 (using the new setting set to either `virtual_sequence` or `sql_sequence`).

roachtest: add test that aggregates orm blacklist failures
cebc811 
The spreadsheet we discussed is unwieldy - hard to edit and impossible to keep
up to date. If we write down blacklists in code, then we can use an approach
like this to always have an up to date aggregation.

So far it seems like there's just a lot of unknowns to categorize still.

The output today:
