FOREIGN TABLE has stable definitions, so there are some issues
that doesn't exist in COPY command:
- when the type of the last column is not a text[]
- when the last column is changed by ALTER FOREIGN TABLE ADD/DROP COLUMN
BTW, those options could be specified in column options rather than table
options. But we don't have column option syntax in the current proposal.
CREATE FOREIGN TABLE arr_text (
i integer OPTION (column 1), -- column position in csv file
t text[] OPTION (column 'all the rest'),
d date OPTION (column 2)
) SERVER file_server
OPTIONS (format 'csv', filename '/path/to/ragged.csv');
