Restore database in PostgreSQL when getting error unsupported version (1.13) in file header

I encountered this problem on pgadmin III and was able to fix it by switcing from pgadmin location to the PostgreSQL binaries location:

In pgadmin :
In Windows 
File menu > Options > Binary Paths, then changed "PG bin path" to postgresql/9.x/bin instead of ProgramFiles/pgadmin.

In Linux do similar process and locate the location of PostgreSQL binaries location and point there instead of pgadmin.

Restore worked fine afterwards.
