Hello!
I would like to know how we can backup certain months old data from
PgSQL and then delete it. The intent is to backup everything that is
older than 2 quarters to a blob storage and delete it, to improve
performance and reduce billing.
1) Postgres does not track the insert/update times of data, so unless
you have fields that track that you will not be able to do that.
2) If you do have a way of telling the times for all the records, are
you sure that removing the data on a time basis will be clean enough
operation that it will not leave the data in a compromised state?
3) Have you considered partitioning? See here:
