Restore Miria PostgreSQL DB – Windows

Note: Restoration method changed for Miria 2021 R2 (3.14) and later, the below procedure cannot be used for those newer versions.

Tested with Miria installed in folder c:\Miria on a Windows Server 2019 Standard.
Standard PostgreSQL port 5433 is used.
Test DB to restore is compressed, named TESTDB_5433_DATA_Backup.bz2 and located in Administrator’s download folder.
