file_fdw_program

This is a backport of a patch (due to land in Postgres 10.0) allowing file_fdw to accept a program option in place of a filename option.

Impelementation

This argument is passed to the COPY command in the exact same way as the FROM PROGRAM is passed, so there is very little coding to enable the option.

Examples

```sql CREATE SERVER file_server FOREIGN DATA WRAPPER file_fdw_program; CREATE FOREIGN TABLE onetwothree(one text, two text, three text) SERVER file_server OPTIONS ( program 'echo one,two,three', format 'csv' ); SELECT * FROM onetwothree; one | two | three -----+-----+------- one | two | three (1 row)

CREATE FOREIGN TABLE fourfivesix(four integer, five numeric(6,2), six date) SERVER file_server OPTIONS ( program 'echo 4,5.5,2066-06-06', format 'csv' ); SELECT * FROM fourfivesix; four | five | six
------+------+------------ 4 | 5.50 | 06-06-2066 (1 row) ```
