I do not want to allow postgres_fdw to set "all" GUCs. Because I think it is very difficult to check the validity of
allinput values.
So, I attached modified the patch so that we can easily add GUC that we can set to postgres_fdw module.
If you wish to add more GUC options to the module, add values to the non_libpq_options[] array of the InitPgFdwOptions
function,
And add the validator code for the GUC in the postgres_fdw_validator function.
Best Regards,
Noriyoshi Shinoda

Maybe we can use multiple "options". Something like:
... OPTIONS ( host 'remhost1', port '5433', dbname 'demodb', option='option1=foo', option='option2=bar' );
