By “qualifiers” I meant the schema names (e.g. resultsDatabaseSchema). Obviously .tmpach_ch_condition is missing a schema, so I thought that schema might be missing from the function invocation. It appears that this is not the case, so this may just be a bug in the query. Can you open an issue here and include the same information. We will address it.
In multithreaded mode, achilles can create temporary tables. Based on your response however you meant to run this in single threaded mode and therefore this is probably unexpected behavior. Again please open and issue.
