Speed up pg_waldump TAP test Several invocations decoded and printed the full WAL range even though the test only needs to confirm that a command form works or that decoding reaches a specific error. Limit those checks to one record, and start the fall-off-the-end checks near the end of the generated WAL.
This change reduces the IPC overhead overall, particularly on Windows, without reducing coverage. I am usually hesitant to backpatch such changes as this is only an improvement, but the gains are too good in terms of IO and runtime, for both the CI and the buildfarm. Based on the numbers provided, the CI takes 30% less time to run the test with this change on Windows (worst case shown on the lists). These tests have been introduced in 96063e28366b.
