   Classification: A / Connector-V2 DuckDB query metadata.
   
   Thanks for withdrawing #12543 rather than merging a patch with regressions. 
I rechecked current `dev` at `d7e9931bea0976547e9730675e7019bbef88ad83`: DuckDB 
table-path discovery uses its native mapper in `DuckDBCatalog`, but query 
discovery still inherits `AbstractJdbcCatalog#getTable(String)`, which 
delegates to the generic `CatalogUtils.getCatalogTable(...)` path. The full 
query-metadata issue therefore remains unresolved. #12592 is intentionally 
limited to timestamp aliases and local values; it is related, but it is not a 
replacement for this issue.
   
   Also, #12508 still has a failing Build and has not entered `dev`. Please do 
not treat its unsigned coverage as delivered and do not revive #12543. A 
replacement PR should be based on the then-current `dev` and include: native 
query metadata for DECIMAL precision/scale, TIMESTAMPTZ, 
UUID/JSON/INTERVAL/HUGEINT, and ARRAY/STRUCT string mapping; regressions for 
the previously working `TIMESTAMP_S`/`TIMESTAMP_MS`/`TIMESTAMP_NS` aliases and 
unsigned boundaries; proof that table-path discovery is unchanged; and a 
query-based Source regression in addition to catalog tests. Please link that 
focused replacement here when it is ready.
