This is the approach I have come to as the most successful for data migrations. I will use tools like Kettle / Talend to get data into a staging table with every column as text, then use SQL to migrate that to a properly typed table. Works much better than trying to work within the constraints of these tools. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
