Description:

Here's an actual error that I received:

"Error moving summary data: Error in up_move_from_stage for control_id
c5bcfbd9-1f20-42c1-bb0c-be626b3c15eb:
insert or update on table "followup_data_flow_by_topic" violates
foreign key constraint "followup_data_flow_by_topic_by_topic_id_fkey2" 23503
CONTEXT: PL/pgSQL function interview.up_move_from_stage(uuid,boolean) line
166 at RAISE"

It's confusing.  I have a "stage" schema and a "interview" schema in the
database.  There is a "followup_data_flow_by_topic'  table in the stage
"schema" and one in the "interview"  schema.  I did just noticed that the
end of the message does include the schema name for the stored procedure -
which by the was created as a  stored procedure, not a function.

Ideally this error message would be clearer if the schema name was included
with the data table or object name.  i.e.

"Error moving summary data: Error in interview.up_move_from_stage for
control_id c5bcfbd9-1f20-42c1-bb0c-be626b3c15eb:
insert or update on table "interview.followup_data_flow_by_topic" violates
foreign key constraint
"interview.followup_data_flow_by_topic_by_topic_id_fkey2" 23503
CONTEXT: PL/pgSQL function interview.up_move_from_stage(uuid,boolean) line
166 at RAISE"
