A quick intro for the impatient. Perhaps a simple example is all you need to get things done.

Suppose this was the definition definition of your table and want to load data to it. For this example, we assume data are already validated - -- pre-validation is a central concept in bulk loading.

Present State

Here is what was already in the exam table. 

=> select * from exam ;
    fn     |   ln   | exam | score
-----------+--------+------+-------
 tambouras | vena   |    4 |    97
 sun       | ugjn   |    6 |    82
The Task

Suppose we need to load new data and erase old data.

SOLUTION

  1. File exam.csv contains our pre-validate new data in csv format.
  2. Now, Write a pgloader.conf configuration file. Done.
