Simplify description of --data-checksums in documentation of initdb

michaelpq · michaelpq · commit 4ed6001d7889 · 2019-07-18T10:06:50.000+09:00
The documentation mentioned that data checksums cannot be changed after initialization, which is not true as pg_checksums can do that with its --enable option introduced in v12. This simply removes the sentence telling so.
