It would appear that this part of the interface is not (yet) implemented. I tried to write
CREATE FOREIGN TABLE a (
b text OPTIONS (column_name 'c')
);
and received
ERROR: invalid option "column_name"
HINT: Valid options in this context are: <none>
The use case is actually quite simple. I'm working with a legacy database that has lots of '0000-00-00 00:00:00' date time values, and you can't always cast to text to work around it. So what I really wanted to do was to have something like:
CREATE FOREIGN TABLE person (
id integer,
birthday date OPTIONS (column_name 'c')
birthday_text text OPTIONS (column_name 'birthday')
);
Which would at least allow me to view bogus dates even if I can't do anything with them. (Not even sure if the foreign cast to text would even work, but I can't think of anything else to try).
it would be great if we could set different postgres column names. postgres_fdw has such option as column_name to set column name to map from
