Thread: pgsql: Fix fetching default toast value during decoding of in-progress
Fix fetching default toast value during decoding of in-progress transactions. During logical decoding of in-progress transactions, we perform the toast table scan while fetching the default toast value for an attribute. We forgot to initialize the flag during this scan to indicate that the system table scan is in progress. We need this flag to ensure that during logical decoding we never directly access the tableam or heap APIs because we check for concurrent aborts only in systable_* APIs.
