Then enter `\e` (or `\edit`) to open an editor (`vi` is default):

Write some query:

Finally, save and quit your editor (e.g. `:wq` in `vi`), and `psql` will run the query you... | You can use this syntax in bash (.sh file):

] | The issue tracking input of localized quotes is <https://github.com/jgm/pandoc/issues/661>.
Meanwhile, I recommend using non-typographic quotes (`"`) and for HTML-output use the `--html-q-tags` option and [some CSS, like](https://developer.mozilla.org/docs/Web/CSS/quotes):
```
q {
quotes: '„' '“';
}
``` | My workaround: I made use of the command line tool `sed` and regular expressions:
First, modify the .Rmd (or .md) file and replace all the German typographic quotation marks with standard quotation marks: (WARNING: commands change the file inplace!)
