2363727 - PostgreSQL table is dropped when a column's data type is changed - SAP PD

Symptom

  • PostgreSQL uses the ALTER TABLE command when changing a column's data type from strings (char, varchar, etc.) to numeric values (int, int2, int4, etc.) and the opposite.
    This command will succeed only if each existing entry in the column can be converted to the new type by an implicit cast.

ALTER TABLE table_name ALTER COLUMN column_name TYPE new_dtype;

  • SAP PowerDesigner drops then recreates the table.
