@JC - I do have ora2pg set up last year in test environment already and that what I suggested team using insert script to run in Postgres. And I am not sure how long it would take to load? 1T data. Though if there's a tool liked MySQL workbench to pull the oracle export data pump and import into MySQL.

You need to create ora2pg conf file with TYPE COPY, and ALLOW <LIST OF TABLES separated by space> and remaining other attributes like ORACLE_DSNORACLE_PWDORACLE_USER
similarly PG_DSNPG_USERPG_PWD etc etc.

In my view ora2pg can do most of the stuff you requested.ora2pg can be used to generate the DDL from oracle to postgres based on attributes set in ora2pg conf file (for example TYPE TABLE, will allow getting oracle DDL in an output file, TYPE COPY will bring the data). No doubt you need to set remaining attributes based on the requirement.
Export to CSV is not required, as mentioned TYPE COPY will do a load of data if you like it to do Direct Data Streaming.As of my limited experience I never encountered any issue on the limit on data being transferred, but definitely the load time vary depending on the environment.

Subject: migrate off oracle data to postgres Hello,
I have a huge data on Oracle, would you please suggest how to migrate all data off Oracle to Postgres? Do I need to export into csv and upload to postgres? Ora2pg is limited data from oracle to postgresql right?
