You could check with Oracle if they provide something like that with their "Golden Gate". What you could do is to have a trigger record all changes to the Oracle table in a separate log table and regularly run a program that pulls those changes from the log table and applies them to a PostgreSQL table, deleting the log entries as it goes. You could write such a thing as PostgreSQL function using oracle_fdw, but you need PostgreSQL 9.3 if you want to update Oracle data that way. Yours, Laurenz Albe
