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

MasaoFujii · MasaoFujii · commit 7a00f50ea631 · 2020-03-03T12:25:05.000+09:00
Previously the documentation explains that WAL segment files start at 000000010000000000000000. But the first WAL segment file that initdb creates is 000000010000000000000001 not 000000010000000000000000. This change was caused by old commit 8c843ff, but the documentation had not been updated a long time. Back-patch to all supported branches.
