Six protocol layers from psql to S3 with PostgreSQL none the wiser.
Strengths
- •v86 x86 emulation + 9P + WebSocket layering is genuinely inventive architecture
- •Same transactional code path handles browser and TCP clients identically
- •Proof that browser VMs can run demanding software like PostgreSQL
Weaknesses
- •Author admits this is exploratory, not for production database use today
- •Requires manually placing PostgreSQL binaries on ZeroFS filesystem
