Hello,

i tried to migrate a database cluster from pg 9.4.1 to 9.5.1 with
pg_upgrade. I got the follwing error:

c:\Temp>"C:\Program Files\PostgreSQL\9.5\bin\pg_upgrade" -b "C:\Program
> Files\PostgreSQL\9.4\bin" -B "C:\Program Files\PostgreSQL\9.5\bin" -

> Files\PostgreSQL\9.5\data" -p 5433 -P 5432 -U postgres

The file loadable_libraries.txt contains:

I tried to copy the dll from the 9.4 version but the interface seems not to
be compatible.

I use postgres under Windows 7 64 Bit.
