Recovery of corrupted database

Our client got virus on database server encrypting the database. They paid and got files decrypted but database wasn’t able to start.

We got the following error:
2017-07-19 10:31:11 CEST LOG: database system was shut down in recovery at 2017-07-19 10:29:00 CEST
2017-07-19 10:31:11 CEST LOG: invalid magic number B549 in log segment 000000010000002E00000015, offset 0
2017-07-19 10:31:11 CEST LOG: invalid primary checkpoint record

2017-07-19 10:31:11 CEST LOG: shutting down
2017-07-19 10:31:11 CEST LOG: database system is shut down

We got past that with executing the “pg_resetxlog -f DATADIR” command.

Now database starts but we cannot connect to it, we get the following error:
2017-07-19 14:11:05 CEST ERROR: invalid page in block 0 of relation global/12369

Can anyone help?
