I have two databases SQLlite and Postgres, SQLite is my local database in it I am saving fingerprint templates that get capture onsite (i.e offline) and my column is of type BLOB. Now I want to sync these templates into Postgres (to the server), so I created a column of type bytea but Postgres is refusing to take BLOB it says there was a syntax error. I am using Qt c++ 5.7 application to do the syncing.
