When I try to migrate down my base using terminal command (migrate -path scripts -database "postgresql://postgres:postgres@localhost:5439/basename?sslmode=disable" -verbose down) I got an error: error: database driver: unknown driver postgresql (forgotten import?). How to fix it?

I think you need to build with specific tag to add the specific driver.
See documentation https://github.com/golang-migrate/migrate/tree/master/cmd/migrate#with-go-toolchain
$ go get -u -d github.com/golang-migrate/migrate/cmd/migrate
$ cd $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
$ git checkout $TAG # e.g. v4.1.0
$ go build -tags 'postgres' -ldflags="-X main.Version=$(git describe --tags)" -o $GOPATH/bin/migrate $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate

For new versions of Golang(Go 1.16+)
- If you want to installed Versioned version e.g:
$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@$TAG
Where TAG=v4.1.0 or TAG=v4.1.x etc
- If you want to installed Unversioned version e.g:
$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest
postgres://postgres:postgres@localhost:5439/basename?sslmode=disable, read the doc carefully.error: database driver: unknown driver postgres (forgotten import?))
