Andrew Dunstan	9f8377f7a2	Add a DEFAULT option to COPY FROM This allows for a string which if an input field matches causes the column's default value to be inserted. The advantage of this is that the default can be inserted in some rows and not others, for which non-default data is available. The file_fdw extension is also modified to take allow use of this option.

Fujii Masao	ecc84b916f	Add regression test for TRUNCATE on foreign table not supporting TRUNCATE. file_fdw doesn't support INSERT, UPDATE, DELETE and TRUNCATE. It has the regression test that confirms that INSERT, UPDATE and DELETE fail on its foreign table, but not TRUNCATE yet. It's better to also test TRUNCATE fails on a foreign table not allowing TRUNCATE, for test coverage. This commit adds that regression test using file_fdw.

Peter Eisentraut	072132f04e	Add header matching mode to COPY FROM COPY FROM supports the HEADER option to silently discard the header line from a CSV or text file. It is possible to load by mistake a file that matches the expected format, for example, if two text columns have been swapped, resulting in garbage in the database. This adds a new option value HEADER MATCH that checks the column names in the header line against the actual column names and errors out if they do not match.

Peter Eisentraut	43f33dc018	Add HEADER support to COPY text format The COPY CSV format supports the HEADER option to output a header line. This patch adds the same option to the default text format. On input, the HEADER option causes the first line to be skipped, same as with CSV.

Tom Lane	dc9c3b0ff2	Remove dynamic translation of regression test scripts, step 2. "git mv" all the input/.source and output/.source files into the corresponding sql/ and expected/ directories. Then remove the pg_regress and Makefile infrastructure associated with dynamic translation. Discussion: https://postgr.es/m/1655733.1639871614@sss.pgh.pa.us	4 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
