text: Title: [BUG] Can't define usage of reserved words on streaming data export
  Body: ### Mage version
  
  0.9.72
  
  ### Describe the bug
  
  I have a streaming pipeline that receives kafka messages, transforms it and then it goes to a postgres data exporter block (which is configured only with the yaml file).
  
  Similar to other issues reported here I'm using some columns that it tries to change, for example `timestamp` throws this error:
  
  ```psycopg2.errors.UndefinedColumn: column "_timestamp" of relation "transactions" does not exist```
  
  I tried to include `allow_reserved_words: true` in the yaml but I get: ```TypeError: PostgresConfig.__init__() got an unexpected keyword argument 'allow_reserved_words'```
  
  Is there a way for me to still use this words in this setup?
