Since 0.17, `@@index` takes an `expression` argument, so the eql_v3.* functional indexes belong in schema.prisma rather than hand-written rawSql operations — the claim that PSL cannot express them predates the upgrade merged in #749. rawSql keeps the ANALYZE (no PSL form exists) and stays documented as the fallback for DDL PSL cannot carry, e.g. CONCURRENTLY. Closes #895
