With zstd compression, prolonged manner may perhaps Enhance the compression ratio, at the price of improved memory use.
However, the tar structure won't assistance compression. Also, when making use of tar format the relative get of desk knowledge objects cannot be altered in the course of restore.
make use of a serializable transaction with the dump, to ensure that the snapshot applied is in step with later databases states; but do that by awaiting a point while in the transaction stream at which no anomalies is usually present, so that There's not a possibility from the dump failing or triggering other transactions to roll back having a serialization_failure. See Chapter 13 To learn more about transaction isolation and concurrency Management.
, ...) VALUES ...). This will make restoration quite sluggish; it is especially helpful for generating dumps that could be loaded into non-PostgreSQL databases.
