If you are not quoting your mixed-case identifiers, then they are not mixed-case. They are being implicitly converted to either lowercase or uppercase depending on your database, and your capitalization is lost. It normally doesn't matter, until you are introspecting your database schema, at which point your code generation generates a Organizationrole protobuf message instead of an OrganizationRole, or your ORM fails to find OrganizationRole because PostgreSQL stored it as organizationrole.

This seems like a terrible feature of Postgres and Oracle (which apparently works the same but oppositely). All other database engines I've used have retained the case of unquoted identifiers.

I haven't used Postgres enough to notice this, it's almost a deal breaker.

I might be tempted to mandate that all identifiers be quoted than deal with half the possible characters for names. Although more likely all code-generation would happen on the application side with DB migrations so the database wouldn't the source of truth for identifier names, anyway.
