Hi, This is with Postgresql 9.3.5. I'm looking at using a COPY command (via jdbc) to do bulk inserts into a table that includes a BIGSERIAL column. Is there a way to mark the data in that column so it gets assigned a new value on entry - akin to the use of 'default' in an INSERT? Some of the rows have values for the serial column, others don't. Or is the only way to use COPY for this task: COPY table_name (columnnameA, columnnameB, columnnameD) FROM source; where the serial column name is omitted? This wouldn't preserve the values for the serial column on rows that have one already. Thanks!
