Hi! I've just written a function for AGE, compiled and installed the
extension, dropped it and created it again. But when I call the function, it
says that it does not exist. Am I doing something wrong? What could be a
solution for this?
I've declared it as the following in the `age--1.3.0.sql` file:
```sql
CREATE FUNCTION ag_catalog.age_adjacency_matrix(graph_name name)
RETURNS void
LANGUAGE c
STABLE
PARALLEL SAFE;
AS 'MODULE_PATHNAME';
```
and defined as the following in the :
```c
PG_FUNCTION_INFO_V1(age_adjacency_matrix);
/*
* Function for returning the graph's adjacency matrix. This adjacency matrix
* stores the number of edges between two nodes. The complexity to check if an
* edge exists within an adjacency matrix is O(1), while the space complexity
* is O(v^2) with v = number of vertices.
*/
Datum age_adjacency_matrix(PG_FUNCTION_ARGS)
{
// Code goes here...
PG_RETURN_VOID();
}
```
Example of query:
```sql
SELECT ag_catalog.age_adjacency_matrix();
ERROR: function ag_catalog.age_adjacency_matrix() does not exist
LINE 1: SELECT ag_catalog.age_adjacency_matrix();
^
HINT: No function matches the given name and argument types. You might need
to add explicit type casts.
