I ran into a variant of this issue trying to use the rust library [sqlx](https://github.com/launchbadge/sqlx) with Apache AGE. sqlx provides compile time query checking by running queries against an actual database instance. This mostly works just fine since AGE is just Postgres under the hood. As part of this they use queries like `EXPLAIN (VERBOSE, FORMAT JSON) <your query>` A query like: `sqlx::query!(r#"SELECT * FROM ag_catalog.create_graph('graph');"#);` works without issues. However queries that return something from the cypher query fail with the error below: ``` sqlx::query!(r#"SELECT * FROM ag_catalog.cypher('graph', $$ CREATE (v:label) RETURN v $$) as (v ag_catalog.agtype)"#); ``` ``` error: error returned from database: cannot display a value of type internal --> src/main.rs:49:5 | 49 | / sqlx::query!(r#"SELECT * FROM ag_catalog.cypher('graph', $$ 50 | | CREATE (v:label) RETURN v 51 | | $$) as (v ag_catalog.agtype)"#); | |___________________________________^ | = note: this error originates in the macro `$crate::sqlx_macros::expand_query` which comes from the expansion of the macro `sqlx::query` (in Nightly builds, run with -Z macro-backtrace for more info) ``` -- This is an automated message from the Apache Git Service.
