**Is your feature request related to a problem? Please describe.**
In the table below, there are many constraints to run the function normally.
And the source file constraints for creating Edge are unrealistic.

**Describe the solution you'd like**
A clear and concise description of what you want to happen.
Using the clause 'Load ~ Match ~ CREATE/MERGE' of neo4j or agensgraph is the
best.
// on Neo4j By CSV Files
LOAD CSV WITH HEADERS FROM 'file:///static/tag_hasType_tagclass_0_0.csv' as
row FIELDTERMINATOR '|'
MATCH (r:tag{id:row.`Tag.id`}), (s:tagclass{id:row.`TagClass.id`})
CREATE (r) - [e:hastype] -> (s);
// on AgensGraph By RDB Table
LOAD FROM forum_containerOf_post as row
MATCH (r:Forum{id:row.forumId}), (s:Post{id:row.postId})
CREATE (r) - [e:ContainerOf] -> (s);
