如何将所有图表放在AgensGraph上？

Question

我想通过删除数据库删除agensgraph上的所有图形。

有查询查找所有图形吗？

agens=# SELECT GRAPHNAME FROM ?????;
 graphname 
-----------
 graph1
 graph2

Answer 1

使用AG_GRAPH表查找所有图形。

然后一张一张地放下图。

agens=# SELECT GRAPHNAME FROM AG_GRAPH;
 graphname 
-----------
 graph1
 graph2
 graph
(3 rows)
agens=# DROP GRAPH GRAPH CASCADE;
NOTICE:  drop cascades to 4 other objects
DETAIL:  drop cascades to sequence graph.ag_label_seq
drop cascades to vlabel ag_vertex
drop cascades to elabel ag_edge
drop cascades to vlabel v
DROP GRAPH
agens=# DROP GRAPH GRAPH1 CASCADE;
NOTICE:  drop cascades to 5 other objects
DETAIL:  drop cascades to sequence graph1.ag_label_seq
drop cascades to vlabel ag_vertex
drop cascades to elabel ag_edge
drop cascades to vlabel v
drop cascades to elabel e
DROP GRAPH
agens=# DROP GRAPH GRAPH2 CASCADE;
