I am trying to use a custom Enum with postgres 8 and I am having a problem. My enum is pretty simple
public enum SubmitType {
 RM("RM","Reader Mail"),
 RE("RE","Reader Email"),
 AD("AD","Advertiser"),
 WR("WR","Writer");
 private String id;
 private String name;
 private SubmitType(String id, String name) {
 this.id = id;
 this.name = name;
 }
 public String getId() {
 return id;
 }
 public String getName() {
 return name;
 }
 public String toString() {
 return id;
 }
}
I then use it in an entity bean 
@TypeDef(
 name="com.pga.recipe.entity.SubmitType",
 typeClass=org.hibernate.type.EnumType.class,
 parameters = {@Parameter(name="enumClass", value="com.pga.recipe.entity.SubmitType")}),
...
@Column(name="submit_type", columnDefinition="varchar(2)")
 @Type(type = "com.pga.recipe.entity.SubmitType")
 public SubmitType getSubmitType() {
 return submitType;
 }
 public void setSubmitType(SubmitType submitType) {
 this.submitType = submitType;
 }
The database table is created correctly and my "submit_type" column is a varchar(2). Then when I try to save an object by using 
setSubmitType(SubmitType.RM)
I get the error message 
"ERROR: column "submit_type" is of type character varying but expression is of type bytea" 
I look at the sql insert statement and it is trying to save the SubmitType enum as binary (<stream of 87 bytes>). Where is the enum object changed to an sql statement? I thought that was in the EnumType.class file, but I added some log statements to EnumType (even some System.out.println) and nothing ever gets fired.
