如何查询 Redshift 以获取特定数据库的所有模式名称

Question

I understand that a database lives inside a schema, but I'm working with an existing design. My old query which targeted postgres is below. I want to recreate it for Redshift. Or some help linking a database to a schema.

select
d.datname database_name
,s.schema_name
from pg_catalog.pg_database d
inner join information_schema.schemata s on s.catalog_name = d.datname
where d.datname = @database_name

Answer 1

So for some reason the "public" schemas are not included in the information_schema.schemata.

My current work-around is:

select cast(@database_name as char(150)) database_name,cast('public' as char(150)) schema_name
union all
select
cast(d.datname as char(150))  database_name
,cast(s.schema_name as char(150)) schema_name
from pg_catalog.pg_database d
inner join information_schema.schemata s on s.catalog_name = d.datname
where d.datname = @database_name
