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	2011-09-16 16:35:51 -04:00
Tom Lane	6e6cc5910b	Make the file_fdw validator check that a filename option has been provided. ... This was already a runtime failure condition, but it's better to check at validation time if possible. Lightly modified version of a patch by Shigeru Hanada.	2011-07-05 18:46:03 -04:00
Tom Lane	7c5d0ae707	Add contrib/file_fdw foreign-data wrapper for reading files via COPY. ... This is both very useful in its own right, and an important test case for the core FDW support. This commit includes a small refactoring of copy.c to expose its option checking code as a separately callable function. The original patch submission duplicated hundreds of lines of that code, which seemed pretty unmaintainable. Shigeru Hanada, reviewed by Itagaki Takahiro and Tom Lane	2011-02-20 14:06:59 -05:00
