Are pregnant women at a greater risk for developing diabetes?

Sort of...: Pregnant women can develop gestational diabetes which can lead to complications for the mother and child, but generally disappears after the end of pregnancy.

Yes: The stress on the maternal system may cause hyperglycemia to be manifested just during pregnancy, then completely resolve after delivery. However, a high percentage of these patients will develop diabetes later in life, not because of the pregnancy, but because they were genetically predisposed.
