Restore from your last backup and then recover to point-in-time by using the redo logs. — doneal24, Sep 16 '16 at 12:32
Good luck restoring the database. Unfortunately the best thing to revert rm is backup. There is a reason why backup is so advised. — MatthewRock, Sep 16 '16 at 13:03
I am sorry for you, but you have almost no chances to restore it. — Serge, Sep 16 '16 at 14:11

Firstly stop using the drive because any changes to the file system will make it harder to recover.

Secondly take a copy of the entire drive using dd or other tools to copy the raw drive to a clean disk.

Next you will need to look at various ext3/4 undeletion tools, always working with the cloned drive never the original. The tools that I know of are:

Next options are:

Send the drive off for data recovery
Look at file carving tools such as photoreq (from the testdisk package)
Accept the loss of data and rebuild with backups as part of the planning process

This process has a low probability of success along with a lot of frustrating effort. — mdpc, Sep 17 '16 at 00:40
