[typing] prefect.server.utilities.database

[mjpieters]

This is a complete refactor of this module.

• Move functions into the sqlalchemy.func namespace so they don't need to be imported everywhere
• Re-use SQLAlchemy's Postgresql JSONB operators by providing SQLite equivalents
• Provide a new function that calculates the difference between timestamps as seconds.

This removes the need for many separate PostgreSQL vs SQLite queries.

👋 hi @mjpieters - in keeping with #16356, can we use prefect.types.DateTime instead of pendulum.DateTime? I appeared to have missed a couple import pendulum; pendulum.DateTime uses

I don't think you missed any; I think there is a mix-up here between pydantic_extra_types.pendulum_dt and pendulum? There are references to pendulum all over prefect still and you can't just replace the pendulum.now() and pendulum.timezone() calls with the two annotated types in prefect.types, I don't think.

I'm closing this PR to re-open a new one, as I accidentally pushed my commits to my fork main branch.
