This:

indicates that you're using v11 or later pg_dump (prior versions
would print "PROCEDURE" not "FUNCTION" here). Don't do that
for this application. In general, the version of pg_dump you use
must be >= the version of the source server, but <= the version
of the server you intend to restore to.
