WalkthroughThe PostgreSQL driver now compiles Cypher through a bounded translation cache. Driver options configure the cache. Schema changes invalidate it, shutdown closes it, and transactions execute cached SQL with request-specific bindings. ChangesPostgreSQL translation cache
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: ⚪ Minimal · up to The PR adds bounded raw-query translation caching while preserving parameter binding and uncached handling for unsupported cases; no actionable merge-blocking risk remains after normal checks and review.

This is where the fast path would be rejected without the disparate translator parameter handling. #129 (comment)

Some declarations may have gotten lost somewhere. Approving to unblock for when that is rectified and CI is green

Description
Adds a bounded PostgreSQL translation cache and connects it to the raw-Cypher query path.
Repeated raw Cypher queries previously paid parsing, optimization, lowering, and rendering
costs on every invocation. Reusing safe compiled translations removes that work while
retaining correct caller-supplied parameter binding.
