By using ... COPY [ BINARY ] table [ WITH OIDS ] FROM { 'filename' | stdin } [ [USING] DELIMITERS 'delimiter' ] [ WITH NULL AS 'null string' ] [BINARY]: If I use it instead of choosing a delimiter, is that safe for copied data and more quick to copy? [WITH OIDS] : If my application didn't use any oid, do I need to specify it? Which one (specify it or not ) will be more quick to copy?
