重新登录AgensGraph后如何访问图？

Question

重新登录后无法访问图形。

我创建了一个新的名为“ graph”的图并访问我的图。 但是，重新登录后无法访问我的图表。

$ agens
agens (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# create graph graph;
CREATE GRAPH
agens=# match (n) return n;
 n 
---
(0 rows)

agens=# \quit
$ agens
agens (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# match (n) return n;
ERROR:  graph_path is NULL
HINT:  Use SET graph_path

我想访问自己的图形。

Answer 1

使用图形之前，必须先设置“ graph_path”。

为避免不便，请使用“更改用户...设置graph_path”将用户绑定到特定图形。

$ agens
agens (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# match (n) return n;
ERROR:  graph_path is NULL
HINT:  Use SET graph_path
agens=# set graph_path to graph;
SET
agens=# match (n) return n;
 n 
---
(0 rows)

agens=# alter user agens set graph_path to graph;
ALTER ROLE
agens=# \quit
$ agens

agens=# match (n) return n;
