Voyager doesn't recognize Hasura's syntax for stored procedures

[dmagda]

I was migrating the following eCommerce application from PostgreSQL:
https://github.com/YugabyteDB-Samples/hasura-ecommerce

The application has a public schema with the app-specific data and hdb_catalog schema with Hasura metadata. The following command was used during the schema export step:

yb-voyager export schema --export-dir $VOYAGER_EXPORT_DIR \
    --source-db-type postgresql \
    --source-db-host 34.23.188.24 \
    --source-db-user postgres \
    --source-db-password 'password' \
    --source-db-name postgres \
    --source-db-schema 'public,hdb_catalog'

The tool exports the following stored procedure of Hasura to the voyager_export_dir\schema\functions\functions.sql file:

CREATE FUNCTION hdb_catalog.gen_hasura_uuid() RETURNS uuid
    LANGUAGE sql
    AS $$select gen_random_uuid()$$; 

The analyze-schema and import schema commands complete succesfully and don't report any issues. But the stored procedure above (and all the others that are defined below it) are not imported. The import fails silently.

As a workaround, the stored procedure's format needs to be changed to the following:

CREATE FUNCTION hdb_catalog.gen_hasura_uuid() RETURNS uuid
LANGUAGE sql
AS $$
        select gen_random_uuid()
$$;
