```markdown ### Result **Review Result: Mergeable** The change correctly uses the database-owned default-schema resolution while preserving explicitly qualified schema behavior. ### Evidence - [`PostgreSQLComDescribeExecutor`](https://github.com/apache/shardingsphere/blob/5de99c6306eca56431a64e0ab85f8216713fa449/proxy/frontend/dialect/postgresql/src/main/java/org/apache/shardingsphere/proxy/frontend/postgresql/command/query/extended/describe/PostgreSQLComDescribeExecutor.java#L159-L163) now resolves unqualified INSERT metadata through `ShardingSphereDatabase.getDefaultSchemaName()`. - [`ShardingSphereDatabase.getDefaultSchemaName()`](https://github.com/apache/shardingsphere/blob/5de99c6306eca56431a64e0ab85f8216713fa449/infra/common/src/main/java/org/apache/shardingsphere/infra/metadata/database/ShardingSphereDatabase.java#L303-L315) returns the actual matched schema name after identifier-aware lookup. - The regression test makes lowercase `"public"` unavailable and verifies that the actual `"PUBLIC"` schema is used, so it would fail with the previous implementation. - Focused verification passed: 20 tests, 0 failures, 0 errors. ### Coverage - Reviewed head: `5de99c6306eca56431a64e0ab85f8216713fa449`. - All 2 authoritative [changed files](https://github.com/apache/shardingsphere/pull/39496/files) were accounted for; GitHub and local triple-dot inventories matched. - Reviewed cluster: default-schema resolution during PostgreSQL prepared-statement description. - PostgreSQL and the related openGauss frontend were checked; openGauss reuses the same describe executor and compatible default-schema contract. - No parser grammar or accepted syntax changed, so parser baselines, syntax documentation, and external syntax evidence were not applicable. - Completed root-cause, blast-radius/contracts, tests/runtime, and final convergence passes with no blocking findings or unresolved code-evidence gaps. - This is a code-scope result only; CI was not reviewed. ``` -- This is an automated message from the Apache Git Service.
