When using a Postgres database to store collected data, the error "Type lo does not exist" appears in the OMNI Server log file when saving Images (Image Capture or Digital Ink) to a binary field of type bytea.

Example log file entry:

2015/07/07 13:55:23.337,12345,98765,-1,4.0.1.0,4.0.1.0,25,1,882,Error Inserting the collected data: ERROR [42704] ERROR: type "lo" does not exist;

Error while executing the query

There is a setting you can change in the ODBC Driver settings to address this problem. 

Set the "bytea as lo" option as shown.
