I agree with Spidey:

1] if you are passing the file with the sql use -f or --file parameter

When you want to execute several commands the best way to do that is to add parameter -f, and after that just type path to your file without any " or ' marks (relative paths works also):

psql -h %host% -p 5432 -U %user% -d %dbname% -f ..\..\folder\Data.txt

It also works in .NET Core. I need it to add basic data to my database after migrations.
