TryUpgradeCheckpointLock()

unique_ptr< StorageLockKey > duckdb::StorageLock::TryUpgradeCheckpointLock

(

StorageLockKey &

lock

)

This is a special method that only exists for checkpointing This method takes a shared lock, and returns an exclusive lock if the parameter is the only active shared lock If this method succeeds, we have both a shared and exclusive lock active (which normally is not allowed) But this behavior is required for checkpointing
