Uncommitted Data

Hi Everyone,

What does PG do with data that has been inserted into a table, but was
never committed? Does the data get discarded once the connection dies?

Thanks

Yes, the transaction will rollback.

The data is there, but is not visible. You can run an explicit VACUUM to
remove the "dead rows", or you can wait for it to be garbage collected
automatically at some point in the future, depending upon your workload.
