WAL contains REDO log information, which means only COMMITTED
transactions will be recovered. Sequentiality of TXID refers to the
start of the transaction. Transactions can therefore be committed in a
different order (meaning that 75666 could for example be committed
before 75634 in your case).
Remember that if you do not specify "recovery_target_inclusive =
false", your txid target will be included in the recovered server.
For further information, I suggest you look at:

Cheers,
Gabriele
