agens-graph - 重新登录AgensGraph后如何访问图表？

Question

重新登录后无法访问图表。

我创建了名为“graph”的新图并访问了我的图。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

我想访问我自己的图表。

Answer 1

您必须在使用图形之前设置“graph_path”。

为避免不便，请使用“alter user ... set 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 (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# match (n) return n;
 n
