v0.5.1

Added

• Added :or_replace support to QuackDB.DDL.create_table/2,3 and support for creating a differently named table from an Ecto schema via QuackDB.DDL.create_table(name, schema, opts).
• Added QuackDB.Profile for DuckDB EXPLAIN (ANALYZE, FORMAT json) query profiles with structured operator helpers, and added :format support to QuackDB.SQL.explain/2.
• Added tests and documentation for Ecto insert-from-query staging/dedupe with returning.

Changed

• Removed public QuackDB.DDL.create_table_as/3; use QuackDB.DDL.create_table/2 or /3 with the :as option instead.

Fixed

• Fixed schema-backed append type inference for parameterized Ecto types such as Ecto.Enum.
• Fixed explicit columns: [...] preservation in schema-backed append inserts.
• Fixed Ecto :map append values by JSON-encoding maps for DuckDB VARCHAR append columns.
• Fixed full schema-backed native append value ordering to follow schema field-source order.
