Amit Kapila 4ec157c150 Fix uninitialized access to InitialRunningXacts during decoding. ... In commit 272248a0c, we introduced an InitialRunningXacts array to remember transactions and subtransactions that were running when the xl_running_xacts record that we decoded was written. This array was allocated in the snapshot builder memory context after we restore serialized snapshot but we forgot to reset the array while freeing the builder memory context. So, the next time when we start decoding in the same session where we don't restore any serialized snapshot, we ended up using the uninitialized array and that can lead to unpredictable behavior. This problem doesn't exist in HEAD as instead of using InitialRunningXacts, we added the list of transaction IDs and sub-transaction IDs, that have modified catalogs and are running during snapshot serialization, to the serialized snapshot (see commit 7f13ac8123).
