执行以下sql：

SELECTns.nspname as schema_name,tab.relname as table_name,cls.relname as index_name,am.amname as index_type,idx.indisprimary as is_primary,idx.indisunique as is_unique
FROMpg_index idx
INNER JOIN pg_class cls ON cls.oid=idx.indexrelid
INNER JOIN pg_class tab ON tab.oid=idx.indrelid
INNER JOIN pg_am am ON am.oid=cls.relam
INNER JOIN pg_namespace ns on ns.oid=tab.relnamespace
WHERE tab.relname = 'ics_check_report'

结果如下：
