A real nice thing about Postgres and Mysql is that in the JVM world the H2 and HSQLDB engines have large compatibility, you can use them in-JVM for unit test speed in many cases. Doesn't help developing the SQL, does help with testing.

Snowflake, on the other hand, is just special.

I assume this can't be done with Oracle DBs

I haven't explored myself, but I would bet they have good Oracle compatibility for at least the subset of semantics they support.
