The backup docs at:
https://www.pgadmin.org/docs/pgadmin4/4.14/backup_dialog.html
say:
"Move the switch next to *$ quoting* to the* Yes position to enable* dollar
quoting within function bodies; if disabled, the function body will be
quoted using SQL standard string syntax.".
But those are the Disable options, so either the text is wrong, or the
switch is inverted.
