不明なPG数値型25

Question

私はPython-Flask、SQL Alchemy、& Postgres qith psycopg2パッケージを使ってプロジェクトを進めています。 プロジェクトはデータベースにデータを正常に保存しますが、オブジェクトをリフレッシュするときに "Unknown PG数値タイプ25"というエラーがスローされます。

 project.second_payment_percent = int(request.form.get("second_payment_percent", 0)) if request.form.get("second_payment_percent", 0) else 0 
     project.second_payment_before = int(request.form.get("second_payment_before", 120)) 
     project.currency_id = int(request.form.get("currency_code")) 
     project.security_deposit = int(request.form.get("security_deposit", 0)) 
     project.apa = int(request.form.get("apa", 0)) 
     project.vat_schema_id = request.form.get("vat_schema") if request.form.get("vat_schema", 0) else None 

     if project.apa > 0: 
      project.security_deposit = int(project.project_price) * int(project.apa)/100 

     db.session.add(project) 
     db.session.commit() 
     db.session.refresh(project) 
     db.session.flush() 

私が手にエラーが

である私は多くのことを試みたが、失敗しています。

テーブルのいずれかのフィールドがテキストで、数値として取得しようとしているようです。

postgres=# select * from pg_type where oid = 25; 
-[ RECORD 1 ]--+--------- 
typname  | text
