我正在尝试使用查询创建架构:
CREATE SCHEMA IF NOT EXISTS hdb_catalog
但发生以下错误:
2019-09-10 13:47:37.025 UTC [129] ERROR: duplicate key value violates unique constraint "pg_namespace_nspname_index"
2019-09-10 13:47:37.025 UTC [129] DETAIL: Key (nspname)=(hdb_catalog) already exists.
2019-09-10 13:47:37.025 UTC [129] STATEMENT:
CREATE SCHEMA IF NOT EXISTS hdb_catalog
怎么可能IF NOT EXISTS
?
