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:  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?
