The following bug has been logged on the website: Bug reference: 16311 Logged by: vamsi krishna Email address: (redacted) PostgreSQL version: 12.1 Operating system: Centos 7.6 Description: Hi PG support, I am having this issue with PostgreSQL 12.1, on Centos 7.6. When I lose server suddenly, I see a lot of empty zero-sized WAL files in the archive logs. I have enabled the archive logs on the .conf. This archive log is present on a DAS LVM disk on the server. Why are there so many empty zero-sized WAL files in the archive logs, why it did not sync? Is this a known issue with PostgreSQL, I have seen the same behavior with PostgreSQL 9.6 as well. I have been deleting these zero-sized WAL files or populating it to 16MB for recovery. What does usually DBA do to tackle these zero-sized WAL files? Thanks and best regards Krishna
