It seems that pg_basebackup should always specify readonly attribute
for the connection.
Your data directory is named standby1, so I suspect
that you are trying to make backup from read-only standby instance of
the base.
Can you check if problem persists in your setup with command
pg_basebackup -v -x -D standby1 \ -d "host=localhost port=5532 user=rep_user readonly=1"

Of course, this shouldn't happen even if libpq is severely misused.
And it is almost evident what should be done to fix it.
But making sure that my patch doesn't interfere with operation of
pg_basebackup is a bit more complicated.
