需要服务器重启的 PostgreSQL 配置项列表
一些 PostgreSQL 配置项 - 通常在 postgresql.conf 中设置 - 需要服务器重启才能生效。
使用视图 pg_settings 列出需要重启的项
SELECT name FROM pg_settings WHERE context='postmaster'
从 PostgreSQL 9.5 开始，pg_settings 包含一个字段 pending_restart，该字段指示需要服务器重启的配置项已更改，并且正在等待重启。
在 PostgreSQL 16 中，这些设置是：
- archive_mode
- autovacuum_freeze_max_age
- autovacuum_max_workers
- autovacuum_multixact_freeze_max_age
