我正在尝试使用 pg_cron 设置 PostgreSQL (v16.1) Docker 容器，但在启动时出现此错误：
2024-02-12 07:15:16.320 UTC [54] ERROR: unrecognized configuration parameter "cron.database_name"
2024-02-12 07:15:16.320 UTC [54] CONTEXT: PL/pgSQL function inline_code_block line 3 at IF
2024-02-12 07:15:16.320 UTC [54] STATEMENT: CREATE EXTENSION pg_cron SCHEMA pg_catalog;
ERROR: unrecognized configuration parameter "cron.database_name"
CONTEXT: PL/pgSQL function inline_code_block line 3 at IF
我在this topic中发现了类似的问题，但所有解决方案似乎都不起作用。其他扩展（即：dblink、pg_partman、pg_jobmon）正在按预期工作。

您是否将“pg_cron”添加到 postgresql.conf 文件中的“shared_preload_libraries”？
