I think the change to the hash functions needs to be called out in the release notes.
Advertising
If anyone stored any results of hashintN, hashfloat8, etc in their database or outside the database those results will have changed. It's fairly unlikely but there could be someone out there doing that. No intervention is required for normal expression indexes using those functions or hash indexes which will be rebuilt during a database upgrade anyways. I don't think hash_any itself changed so this wouldn't affect hashtext or any hash function which was already using hash_any. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
