Hi,


replication_slot_catalog_xmin is not explictly initialized to InvalidTransactionId.


Normally, there isn't an issue with this because a freshly mmap'd memory is zeroed, and the value of InvalidTransactionId is 0.

If the memory was not 0 for whatever reason, VACUUM would not behave as expected.


See attached patch.


Thanks,

Yi Wen
