Options for Postgres FDW
I´m trying to insert/update some tables using FDW. I´m having problems when I
want to use default values and triggers.
For columns with default values, if I drop that column on foreign table
definition is fine for inserts but I cannot use that column for
updates/selects because it doesn´t exist on foreign table definition.
For triggers, there is a way to define search_path for that
server/connection ? Because suppose I´ve used "import foreign schema
CustomerSchema", when I do some insert/update on any table of this schema,
if that table calls a trigger which needs another table, that trigger
doesn´t sees that table because it´s using pg_catalog schema. The only way
to solve this is defining search_path when starting all triggers ?

Additionally, there is a list of all options for create foreign server and
create foreign table ?

That is going to depend on the FDW. Options that make sense for
connecting to a database make not make sense for a file based FDW. For
postgres-fdw see:

Don't drop it?
