Hello,

Currently we can not moves data from a file to a table based on some
condition on a certain column but I think there are many use case for it
that worth supporting. Attache is a patch for escaping a row that does not
satisfy WHEN condition from inserting into a table and its work on the top
of commit b68ff3ea672c06

and the syntax is

COPY table_name [ ( column_name [, ...] ) ]

FROM { 'filename' | PROGRAM 'command' | STDIN }

[ [ WITH ] ( option [, ...] ) ]

[ WHEN condition ]

comment ?

Regards

Surafel
