字段结构 PostgreSQL 18
pg_publicationPostgreSQL 19 beta 3 是预发布快照,结构在正式发布前仍可能变化。
| 字段 / COLUMN | 类型 / TYPE | 说明 / DESCRIPTION |
|---|---|---|
oid |
oidNOT NULL |
Row identifier |
pubname |
nameNOT NULL |
Name of the publication |
pubowner |
oidNOT NULL |
Owner of the publication引用:pg_authid.oid |
puballtables |
booleanNOT NULL文档原写法:bool |
If true, this publication automatically includes all tables in the database, including any that will be created in the future. |
pubinsert |
booleanNOT NULL文档原写法:bool |
If true, INSERT operations are replicated for tables in the publication. |
pubupdate |
booleanNOT NULL文档原写法:bool |
If true, UPDATE operations are replicated for tables in the publication. |
pubdelete |
booleanNOT NULL文档原写法:bool |
If true, DELETE operations are replicated for tables in the publication. |
pubtruncate |
booleanNOT NULL文档原写法:bool |
If true, TRUNCATE operations are replicated for tables in the publication. |
pubviaroot |
booleanNOT NULL文档原写法:bool |
If true, operations on a leaf partition are replicated using the identity and schema of its topmost partitioned ancestor mentioned in the publication instead of its own. |
pubgencols |
"char"NOT NULL文档原写法:char |
Controls how to handle generated column replication when there is no publication column list: n = generated columns in the tables associated with the publication should not be replicated, s = stored generated columns in the tables associated with the publication should be replicated. |
标记“隐式列”的字段不包含在 SELECT * 中;部分早期统计视图由同版本源码补全,额外来源会显示在字段说明中。
通用系统列 6
PostgreSQL 提供的系统属性,通常不在 SELECT * 中展开。单独保留,不与普通字段混算。
| 字段 | 类型 | attnum |
|---|---|---|
tableoid | oid | -6 |
cmax | cid | -5 |
xmax | xid | -4 |
cmin | cid | -3 |
xmin | xid | -2 |
ctid | tid | -1 |
字段演化矩阵
悬停查看字段类型存在新增 / 类型或属性变化移除
9.0 是收录基线;基线中已存在的字段不标记为新增。矩阵按字段名称对齐,重命名显示为旧字段移除与新字段新增。
