> REPL DUMP is replication all OpenXacts, even when they are from other non replicated databases. This wastes space in the dump, and ends up opening unneeded transactions during REPL LOAD.
>  
> Add a config property for replication that filters out OpenXact events during REPL DUMP. During REPL LOAD, the txns can be implicitly opened when the ALLOC_WRITE_ID is processed. For CommitTxn and AbortTxn, dump only if WRITE ID was allocated.
