Maxim Solodovnik created OPENJPA-2971:
-----------------------------------------
Summary: storeCharsAsNumbers default flip breaks existing schemas
Key: OPENJPA-2971
URL: https://issues.apache.org/jira/browse/OPENJPA-2971
Project: OpenJPA
Issue Type: Sub-task
Components: jpa
Affects Versions: 4.2.0
Reporter: Maxim Solodovnik
Fix For: 4.2.0
Discussion thread:
https://github.com/apache/openjpa/pull/144#discussion_r3683003316
**(medium)** Flipping `storeCharsAsNumbers` to false for PostgreSQL >= 9
changes the default mapping for existing applications: char fields previously
stored in INTEGER columns will now map/validate as CHAR, so schemas created by
older OpenJPA versions fail validation or read wrongly after an upgrade.
Intended compatibility break? Should be release-noted and overridable.
