show :: EscapeCopyValue -> String

showList :: [EscapeCopyValue] -> ShowS

escapeCopyRow :: [EscapeCopyValue] -> ByteString

Escape a row of data for use with a COPY FROM statement. Include a trailing newline at the end.

This assumes text format (rather than BINARY or CSV) with the default delimiter (tab) and default null string (\N). A suitable query looks like:

COPY tablename (id, col1, col2) FROM stdin;
