postgresql - 相当于 `pg_rules`中的 `information_schema`

Question

我知道，information_schema 是 SQL 标准，RULES 是 Postgres SQL 扩展。

还有，有没有办法使用 information_schema 列出所有可用规则？

Answer 1

不，根据documentation :

The information schema views do not, however, contain information about PostgreSQL-specific features; to inquire about those you need to query the system catalogs or other PostgreSQL-specific views.
