chrislu	ec1e74a6e8	feat: Add Parquet logical types to mq_schema.proto ... Added support for Parquet logical types in SeaweedFS message queue schema: - TIMESTAMP: UTC timestamp in microseconds since epoch with timezone flag - DATE: Date as days since Unix epoch (1970-01-01) - DECIMAL: Arbitrary precision decimal with configurable precision/scale - TIME: Time of day in microseconds since midnight These types enable advanced analytics features: - Time-based filtering and window functions - Date arithmetic and year/month/day extraction - High-precision numeric calculations - Proper time zone handling for global deployments Regenerated protobuf Go code with new scalar types and value messages.	2025-09-03 07:18:58 -07:00
chrislu	d60c542ecc	feat: Replace pg_query_go with lightweight SQL parser (no CGO required) ... - 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.	2025-09-03 07:11:18 -07:00
