If you try to insert NULLs into a nonnull field you should get an error. If you have unquoted empty strings, and are not using the empty string as the NULL marker, then you can just not set the NULL code to be the empty string. If you need to turn this on and off by column, then perhaps it would be better to do that externally. As for setting default values, I think that is a good idea. I suggested a while back. There could be another keyword, DEFAULT, on the COPY FROM command that is used to define a code that will be replaced by the default value (or NULL if there is no default for a column) similar to how the NULL code is replaced by NULL. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
