- Remove github.com/pganalyze/pg_query_go/v6 dependency to avoid CGO requirement
- Implement lightweight SQL parser for basic SELECT, SHOW, and DDL statements
- Fix operator precedence in WHERE clause parsing (handle AND/OR before comparisons)
- Support INTEGER, FLOAT, and STRING literals in WHERE conditions
- All SQL engine tests passing with new parser
- PostgreSQL integration tests can now build without CGO
The lightweight parser handles the essential SQL features needed for the
SeaweedFS query engine while maintaining compatibility and avoiding CGO
dependencies that caused Docker build issues.
The pg_query_go library requires CGO to be enabled as it wraps the libpg_query C library.
Added gcc and musl-dev dependencies to the Docker build for proper compilation.
