我在postgresql.conf 里配置了 full_page_writes 是 on，在gsql查询full_page_writes 也是on， 但是查看控制文件，full_page_writes 是 off，这是怎么回事？ 这种情况 full_page_writes 到底是on还是off？

[postgres@pg_155 hadb-opengauss]$ gsql -p31001 -r gsql ((openGauss 3.0.0 build b592536d) compiled at 2022-04-06 17:04:16 commit 0 last mr debug) Non-SSL connection (SSL connection is recommended when requiring high-security) Type "help" for help.

openGauss=# show full_page_writes; full_page_writes ------------------ on (1 row)
