STATISTICS VIEW · 统计视图

pg_stat_gssapi

The pg_stat_gssapi view will contain one row per backend, showing information about GSSAPI usage on this connection. It can be joined to pg_stat_activity or pg_stat_replication on the pid column to get more details about the connection.

字段结构 PostgreSQL 18

pg_stat_gssapi

字段 / COLUMN	类型 / TYPE	说明 / DESCRIPTION
`pid`	`integer`	Process ID of a backend
`gss_authenticated`	`boolean`	True if GSSAPI authentication was used for this connection
`principal`	`text`	Principal used to authenticate this connection, or NULL if GSSAPI was not used to authenticate this connection. This field is truncated if the principal is longer than NAMEDATALEN (64 characters in a standard build).
`encrypted`	`boolean`	True if GSSAPI encryption is in use on this connection
`credentials_delegated`	`boolean`	True if GSSAPI credentials were delegated on this connection.

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。
