Tom Lane	21734d2fb8	Support writable foreign tables. ... This patch adds the core-system infrastructure needed to support updates on foreign tables, and extends contrib/postgres_fdw to allow updates against remote Postgres servers. There's still a great deal of room for improvement in optimization of remote updates, but at least there's basic functionality there now. KaiGai Kohei, reviewed by Alexander Korotkov and Laurenz Albe, and rather heavily revised by Tom Lane.	13 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	14 years ago
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.	14 years ago
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	15 years ago
