Problem summary
Your PostgreSQL export can't change the destination table because the Funnel database user doesn't own it.
Error message or symptoms
The export fails with an error that contains:
must be owner of table
When does this occur
You export to a table that another database user created, and then add a field to the export so Funnel needs to add a column.
Root cause
PostgreSQL only lets the table owner add columns. When the Funnel user doesn't own the table, Funnel can't update its structure.
Solution
Do one of the following, then run the export again:
Transfer ownership: Make the Funnel database user the owner of the table.
Use a new table: Change the export's Table name template to a table that doesn't exist yet. Funnel creates the table on the next run.
To transfer ownership, run this command. Replace the schema, table and user names with your own.
ALTER TABLE <schema>.<table> OWNER TO funnel_export;
