User defined functions

Users may add custom functions to the AGE. When using the Cypher function, all function calls with a Cypher query use the default namespace of: ag_catalog. However if a user want to use a function outside this namespace, they may do so by adding the namespace before the function name.

Syntax: namespace_name.function_name

Query

SELECT *
FROM cypher('graph_name', $$
RETURN pg_catalog.sqrt(25)
$$ as (result agtype);

Result:
