Good Afternoon everyone, I've got a knotty problem, I have a mature Postgres database that has over 500 tables, and is too large to dump. 大家下午好，我遇到了一个棘手的问题，我有一个成熟的Postgres数据库，该数据库有500多个表，并且太大而无法转储。 When a product is added to the database a new line is created in many tables and I'd like to check what information is added in order to replicate the functionality in a new piece of software. 将产品添加到数据库后，会在许多表中创建新行，我想检查添加了哪些信息，以便在新软件中复制功能。 The reason is the existing software interface is very old and unfriendly so we are replacing it. 原因是现有的软件界面非常旧且不友好，因此我们将其替换。 I can't very easily use the approach suggested here: Search entire postgres database? 我不太容易使用这里建议的方法：搜索整个postgres数据库？ . 。 Can anyone suggest another solution? 谁能建议其他解决方案？

I should clarify i can't modify the database at all, until we have reliably replaced the existing interface and that won't be for months yet. 我要澄清的是，在我们可靠地替换了现有接口之前，根本无法修改数据库，而且这种情况将持续数月之久。

Thanks 谢谢

You can set log_statement = 'all' for the short time when you run your experiment. 您可以在运行实验时将log_statement = 'all'为很短的时间。 Make sure that your log_line_prefix contains %c . 确保您的log_line_prefix包含%c 。 Then you can track all SQL statements that belong to one database session. 然后，您可以跟踪属于一个数据库会话的所有SQL语句。
