I just worked out the query which does the job and wanted to post it so
if anyone wants in the future can refer to this thread. Here's the query:
SELECT pg_catalog.pg_class.relacl AS permissions FROM
pg_catalog.pg_class WHERE pg_catalog.pg_class.relname = 'table_name' AND
pg_catalog.pg_class.relnamespace IN (SELECT pg_catalog.pg_namespace.oid
FROM pg_catalog.pg_namespace WHERE pg_catalog.pg_namespace.nspname =
'schema_name');
