If the transactions are commited , i don't think you can recover all those records back.

NO,i have not committed the transaction

NO,i have not committed the transaction

if you're begginer you probably do not understand what mnsprasad says because
the question is if you start the transaction using 'begin transaction' command before deleting rows and and do not confirm that transaction. I'm afraid you do not, you just delete rows (using delete command) if so it means that the transaction have been confirmed.
When you delete rows they phisically still exists in a table until you call the 'vacuum' command, but i don't know if there is a way do restore that rows, i do not know a software which do that (postgres do not).
WAL is a way to do a incremental buckups, using it you can restore a database. More on postgresql.org.
