make installcheck-world:  not tested
Implements feature:       not tested
Spec compliant:           not tested
Documentation:            tested, passed

The issue has been verified using below steps:
1. $ initdb -D /home/test/PG122DATA/data
2. $ ls -l /home/test/PG122DATA/data/pg_wal/
total 16388

drwx------ 2 test test     4096 Feb 18 12:07 archive_status

The first WAL segment file created by initdb is "000000010000000000000001", not "000000010000000000000000".

Commits

  1. Fix the name of the first WAL segment file, in docs.

  2. Bootstrap WAL to begin at segment logid=0 logseg=1 (000000010000000000000001)
