Обсуждение: pgsql: Fix assertion failure when updating full_page_writes forcheckpo
Fix assertion failure when updating full_page_writes for checkpointer. When the checkpointer receives a SIGHUP signal to update its configuration, it may need to update the shared memory for full_page_writes and need to write a WAL record for it. Now, it is quite possible that the XLOG machinery has not been initialized by that time and it will lead to assertion failure while doing that. Fix is to allow the initialization of the XLOG machinery outside critical section. This bug has been introduced by the commit 2c03216d83 which added the XLOG machinery initialization in RecoveryInProgress code path.
