Because $ is escaped, the results are different when the same command is
executed in psql and internally.
I would like to ask how to solve this problem, or why there is this
difference?

When passing a quoted argument to psql, it is necessary to account for the
shell's interpretation, for example:
$ echo "foo $1"
foo
$ echo "foo \$1"
foo $1
