+===============================================================================
+Feature: #67290 - DBAL: DBMS specific conversion between Meta/MySQL field types
+===============================================================================
+
+Description
+===========
+
+DBAL did a generic translation between MySQL native and DBMS specific field types.
+
+The translation of field types has been enhanced to allow more specific conversions per DBMS driver.
+Overrides for PostgreSQL have been added with optimized mappings for BLOB, SERIAL, DOUBLE and INTEGER columns.
+
+
+Impact
+======
+
+Running PostgreSQL, the Upgrade Wizard in the Install Tool will show a lot of field alterations as the optimized mappings will be used.
