Document how to implement POST support in authorization proxies to avoid HTTP 414 errors with large WHERE clauses. Includes: - POST body format and accepted parameters - Security guidance: which parameters proxies must set server-side vs. which are safe to pass through from clients - Complete proxy implementation example with GET/POST handling - Client configuration examples for ShapeStream and TanStack DB https://claude.ai/code/session_01MC34oGnC3Rqy4Jhsic59DY
Make the deprecation notice more prominent in both the warning box and the backwards compatibility section. https://claude.ai/code/session_01MC34oGnC3Rqy4Jhsic59DY

Electric combines main shape WHERE (URL) with subset WHERE (POST body) using AND, so subset queries can only narrow results, never widen them. Updated documentation to: - Explain how WHERE clauses are combined - Clarify that POST body subset params are safe to forward from clients - Simplify the proxy example to forward client body directly - Move subset params to "safe to pass through" section https://claude.ai/code/session_01MC34oGnC3Rqy4Jhsic59DY
