Hello Thomas,
See chapter 8.7.
Your array "TestFields" contains the internal enum references that are
converted to the defined values by cross referencing to the catalogue
table pg_enum.
I think you will have to add another column to the table as an array of
text, write a little program to cross reference the TestFields array to
pg_enum and update the new column with the textual representation of
the "enum's", then alter your app accordingly.
HTH,
