[postgis-users] Input on upgrade to GIS database

[Onyx]

Daniel Faivre, Jeremy Sears, Darren Houston, thank you for your input.  OK,
so, with your help, I have been able to bring up _most_ of our data
successfully in the new database.  But, I am having problems with the data
contained within the tables of type PostGIS geometry.

Originally, the table contained something like:

SRID=4326;MULTIPOLYGON(((-105.499999977881 40.5 0,-105.499999977881
40.9999999185093 0,-105.000000006985 40.9999999185093 0,-105.000000006985
40.5 0,-105.249999999884 40.5 0,-105.499999977881 40.5 0)))


Now, after the upgrade and xfer of data, the table contains:

01060000A0E61000000100000001030000800100000006000000FA3FE8FFFF5F5AC000000000
004044400000000000000000FA3FE8FFFF5F5AC0040051FFFF7F444000000000000000000680
070000405AC0040051FFFF7F444000000000000000000680070000405AC00000000000404440
00000000000000001DE0FFFFFF4F5AC000000000004044400000000000000000FA3FE8FFFF5F
5AC000000000004044400000000000000000


Any ideas why and how to fix?
