Andrew Dunstan	3b5e03dca2	Provide a FORCE NULL option to COPY in CSV mode. This forces an input field containing the quoted null string to be returned as a NULL. Without this option, only unquoted null strings behave this way. This helps where some CSV producers insist on quoting every field, whether or not it is needed. The option takes a list of fields, and only applies to those columns. There is an equivalent column-level option added to file_fdw. Ian Barwick, with some tweaking by Andrew Dunstan, reviewed by Payal Singh.	12 years ago
Tom Lane	86a3f2d492	Add FORCE_NOT_NULL support to the file_fdw foreign data wrapper. This is implemented as a per-column boolean option, rather than trying to match COPY's convention of a single option listing the column names. Shigeru Hanada, reviewed by KaiGai Kohei	15 years ago

Provide a FORCE NULL option to COPY in CSV mode.

This forces an input field containing the quoted null string to be
returned as a NULL. Without this option, only unquoted null strings
behave this way. This helps where some CSV producers insist on quoting
every field, whether or not it is needed. The option takes a list of
fields, and only applies to those columns. There is an equivalent
column-level option added to file_fdw.

Add FORCE_NOT_NULL support to the file_fdw foreign data wrapper.

This is implemented as a per-column boolean option, rather than trying
to match COPY's convention of a single option listing the column names.
