"man psql" \set documentation error

Running an application and \set'ing its output in a variable requires use of
the backtick '`' operator.  Under the heading "SQL INTERPOLATION", the
examples should be as follows (the difference being use of backticks instead
of single quotes around the command to be executed):

Current (wrong):
       testdb=> \set content '\'' 'cat my_file.txt' '\''

Correct:
       testdb=> \set content '\'' `cat my_file.txt` '\''



Current (wrong):
       testdb=> \set content 'sed -e "s/'/\\\\\\'/g" < my_file.txt'

Correct:
       testdb=> \set content `sed -e "s/'/\\\\\\'/g" < my_file.txt`
