…s 13-17 - Add BaseTransformer abstract class following deparser visitor pattern - Implement version-specific transformers (v13-to-v14, v14-to-v15, v15-to-v16, v16-to-v17) - Add ASTTransformer orchestrator for chaining transformations - Use dynamic method dispatch with node type names (AlterTableStmt, A_Const, etc.) - Handle wrapped vs inlined node types correctly - Add comprehensive test coverage with 21 passing tests - Support full transformation pipeline from PostgreSQL v13 to v17 Key transformations implemented: - v13→v14: Pass-through (no changes needed) - v14→v15: A_Const restructuring, String/Float/BitString field renames, AlterPublicationStmt changes - v15→v16: Advanced Var and Aggref handling - v16→v17: Pass-through (no changes needed) All tests passing: 5 test suites, 21 tests total Co-Authored-By: Dan Lynch <[email protected]>
…ansformation - Replace placeholder PG13ToPG17Transformer with real implementation using ASTTransformer - Add complete 4-step workflow: parse→transform→deparse→parse→compare - Fix A_Const transformation from nested val.String.str to flattened sval.sval structure - Handle ParseResult structure with version update (130008→170004) and stmt transformation - Add semantic equality verification using cleanTree for AST comparison - Support case-insensitive SQL keyword comparison for formatting differences - All 38 tests passing including critical A_Const structure changes test The end-to-end integration test now demonstrates the complete transformation pipeline from PostgreSQL v13 ASTs to v17 ASTs with semantic equivalence verification.

- Fixed A_Const method in V13ToV14Transformer to create empty ival object {} for zero values instead of { ival: 0 }
- Updated SelectStmt method in V14ToV15Transformer to handle both wrapped and direct SelectStmt structures in larg/rarg nodes
- This resolves the A_Const ival transformation issue that was causing CTE test failures
- Still working on SelectStmt nested field issues for complete test coverage

- Add BaseTransformer with dynamic visitor pattern for AST node transformations - Implement version-specific transformers: V13ToV14, V14ToV15, V15ToV16, V16ToV17 - Add PG13ToPG17Transformer for complete transformation pipeline - Fix A_Const structure changes (val.String.str → sval.sval) in PG14→PG15 - Handle AlterTableStmt objtype field transformation in PG13→PG14 - Preserve RECURSIVE keyword in Common Table Expressions (CTEs) - Add SelectStmt withClause handling to maintain CTE metadata - Implement CreatePublicationStmt transformation (tables → pubobjects) - Add comprehensive field preservation for RangeVar and TypeName nodes - Support FuncCall, WindowDef, and other complex node transformations Current status: 7/15 tests passing, remaining failures are mostly SQL formatting differences in deparser output rather than AST structure issues.
