There is no problem. The quotes are NOT part of the value or in other words they are not stored in the DB. They are only used in ruby to designate a string value (the actual value is between the quotes).
PgAdmin happens to display '' for an empty string to differentiate an empty string from a NULL value. NULL values are displayed as empty cells in pgAdmin it would get confusing if an empty string also resulted in a empty cell.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
