For Postgres, I keep getting this error multiple times even though I have already set the location of the bin folder to the path variable in Windows 8. Is there something else I
Make sure that the path actually leads to the executables. I'm using version 11 and it did not work until this was set as the path:
C:\Program Files\PostgreSQL\11\bin\bin
Maybe this is how version 11 is structured or I somehow botched the installation but I haven't had a problem since.
