> 2019-05-17 06:41:19.954 UTC [11] FATAL: SMgrRelation hashtable corrupted Yes, this is probably the same issue reported in https://www.postgresql.org/message-id/15672-b9fa7db326982...@postgresql.org https://www.postgresql.org/message-id/15684-4ef33de3271cf...@postgresql.org The good news is that the underlying ALTER TABLE bug is fixed in 11.3. The bad news is that your database is probably toast anyway --- an update won't undo the catalog corruption that is causing the WAL replay crash. I hope you have a recent backup to restore from. regards, tom lane
