我想从受限用户(在Postgres9.3上)更新pg_catalog.pg_cast。但是,运行我需要的查询:
update pg_cast set castcontext = 'i' where oid in ( select c.oid from pg_cast c inner joinpg_type src on src.oid = c.castsource inner join pg_type tgt on tgt.oid = c.casttarget wh
我有一个依赖于表的视图: create view hello_v as select * from hello;要从视图名称中检索被引用的表名,我认为pg_class和pg_depend表可能会很有用。对表进行截断会导致pg_depend中没有条目。
如何返回等于pg_catalog.relfilenode的pg_depend.refobjid?c inner join pg_catalog.pg_depend d on d.refobjid = c.relfileno
