From 0550c21d67edc40a3c29c29f930d03a45cf65483 Mon Sep 17 00:00:00 2001 From: Jim Castillo Date: Mon, 12 Jan 2026 15:21:37 -0800 Subject: [PATCH] Add comprehensive PostgreSQL catalog compatibility to enable Metabase and Grafana to connect and discover tables in DuckLake mode. Key changes: Schema remapping for DuckLake: - Remap public.* table references to main.* (DuckLake uses main schema) - Remap public.* column references in SELECT clauses - Add ORDER BY 1 workaround for LIMIT queries without ORDER BY (prevents DuckLake from reading stale data files) New pg_catalog views: - pg_attribute: Column metadata for table discovery - pg_type: Comprehensive type OID mapping (~30 PostgreSQL types) - pg_index: Primary key discovery with synthetic PKs for DuckLake - pg_constraint: Constraint metadata stub - pg_description: Object descriptions stub - pg_attrdef: Column defaults stub - pg_proc: Function metadata stub - pg_tables/pg_views: Schema mapping from main to public New functions/macros: - current_schemas(bool): Schema search path - _pg_expandarray(arr): Array expansion for JDBC PK discovery - has_schema_privilege, has_table_privilege, has_any_column_privilege - format_type, obj_description, col_description enhancements Regex operator fixes: - Convert PostgreSQL regex operators (~, ~*, ) to DuckDB regexp_matches() function calls - Handle case-insensitive variants with (?i) flag - Fix JDBC escaped operator syntax (\~,\!~) Other improvements: - DUCKGRES_TABLE_LIMIT env var for faster testing cycles - SQL injection fix in R2 secret creation (escape single quotes) - Recreate pg_tables after DuckLake attachment for proper metadata - Add duckgres.yaml.example config template - Update .gitignore to exclude credential filesUpdate for Spencer --- .gitignore | 15 + CLAUDE.md | 10 +- duckgres.yaml.example | 42 + main.go | 28 +-
