Add experimental support for PGLite, an embedded PostgreSQL that runs
in WebAssembly via wazero. This allows database-backed type analysis
without requiring a running PostgreSQL server.
Changes:
- Add 'pglite' experiment flag (SQLCEXPERIMENT=pglite)
- Add PGLite configuration in analyzer config (url, sha256)
- Create pglite analyzer package that uses wazero runtime
- Wire PGLite analyzer into compiler when experiment is enabled
To use PGLite analyzer, enable the experiment and configure it:
SQLCEXPERIMENT=pglite sqlc generate
sqlc.yaml:
sql:
- engine: postgresql
analyzer:
pglite:
url: "file://path/to/pglite.wasm"
sha256: "..."

Add integration tests that verify the PGLite analyzer works end-to-end: - Mock WASM module that parses CREATE TABLE and SELECT statements - Tests for SELECT *, SELECT with parameters, specific columns - Tests for multiple tables - Tests for analyzer close/cleanup The mock WASM module implements the JSON protocol expected by the analyzer and can parse simple PostgreSQL schemas and queries. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
