我无法从“Discourse 3.5.0.beta9-dev - 04dbc622ab1e0197d16703ba47cf005ec93697ee”恢复到当前版本（6f06709643fa5e2253606c46f79d089ca3393ac9）

invalid command \restrict
EXCEPTION: psql failed: invalid command \restrict
如果我从 database_restorer 中删除这些 printf 命令，它就可以工作：
<<~CMD
(
printf '%s\n' "\restrict #{nonce}"
#{sed_command}
printf '%s\n' "\unrestrict #{nonce}"
) | #{self.class.psql_command} 2>&1
CMD
看起来像是这个提交。
在我进行备份的版本（一个 cdck docker 容器）中，我有这个：
PostgreSQL 15.13 (Debian 15.13-1.pgdg120+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit
而这是我尝试恢复的地方（在本地运行 pg15 的开发站点）：
PostgreSQL 15.13 (Ubuntu 15.13-1.pgdg22.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, 64-bit
我不明白这段代码试图做什么，所以我很困惑。
