1) Postgres version?

2) Data going into single table or multiple tables?

3) What is the time frame you are trying to achieve?

4) What techniques have you tried?

5) If you need only 1GB why the 400GB number?

Hello,

Sorry 400GB was a typo. Its 400 MB Details are below:

1) Postgres version?
9.6

2) Data going into single table or multiple tables?
Single table having Multiple columns

3) What is the time frame you are trying to achieve?
As quick as possible. 

4) What techniques have you tried?
Insert into with With statement, inserting 2000000 rows at a time. This takes 40 mins.

5) If you need only 1GB why the 400GB number?
That was 400MB. M checking size using \l+ option.


Thanks.
