hi, guys,
I am looking for a couple pointers here about fdw, and how to change
the option values during CREATE table time.
I am using postgres-xc-1.2.1 right now. For example, it contains
file_fdw, whose create-table-stmt looks like:
CREATE FOREIGN TABLE t1(....)
SERVER file_server
OPTIONS(format 'text',filename *'testing.txt'*);
I would like to replace the 'testing.txt' with absolute path like
'/user/testor1/testing.txt', and make sure the new value is saved in
pg_foreign_table; the file_fdw_validator is used to validate the
options, but is there a way to replace the optionValue here? And get
the new value stored in pg_foreign_table?
Thanks
BTW, in my real use case, I am trying to interpret a hdfs file and
would need to save some hostname/port information in the option value,
which not necessary specified by user.
This is the wrong list to ask this - it's a usage question that belongs
on pgsql-general
See the documentation for ALTER FOREIGN TABLE.
cheers
andrew
