How to drop property constraint on AgensGraph? - agens-graph

Question

I want to drop property index on AgensGraph.
agens=# create vlabel v;
CREATE VLABEL
agens=# create elabel e;
CREATE ELABEL
agens=# create property index on v ( id );
CREATE PROPERTY INDEX
agens=# create property index on e ( id );
CREATE PROPERTY INDEX
agens=# drop property index on v ( id );
ERROR: syntax error at or near "on"
LINE 1: drop property index on v ( id );
^
agens=# drop property index on e ( id );
ERROR: syntax error at or near "on"
LINE 1: drop property index on e ( id );
^
But, there is some problem on grammar.

Answer 1

Name of property index is created automatically at creation time.
You can use '\dGe' and '\dGe' for find structure of labels.
agens=# \dGv v
List of labels
Graph | Name | Type | Owner
-------+------+--------+-------
graph | v | vertex | agens
(1 row)
Vertex label "graph.v"
--
Property Indexes:
"v_id_idx" btree (id)
Inherits: graph.ag_vertex
agens=# \dGe e
List of labels
Graph | Name | Type | Owner
-------+------+------+-------
graph | e | edge | agens
(1 row)
Edge label "graph.e"
--
Property Indexes:
"e_id_idx1" btree (id)
Inherits: graph.ag_edge
After search index name, drop property index next.
agens=# drop property index v_id_idx;
DROP PROPERTY INDEX
agens=# drop property index e_id_idx1;
DROP PROPERTY INDEX
