There's a basic test for postgres_fdw in patch 0003, just testing the
syntax and validation.
A manual end-to-end test is pretty straightforward:
-- on publisher
create table foo(i int primary key);
create publication pub1 for table foo;
insert into foo values(42);
-- on subscriber
create extension postgres_fdw;
create table foo(i int primary key);
create server server1
foreign data wrapper postgres_fdw
options (host '/tmp', port '5432', dbname 'postgres');
create user mapping for u1 server server1
options (user 'u1');
select pg_conninfo_from_server('server1','u1',true);
create subscription sub1 server server1 publication pub1;
I don't think we need to add an end-to-end test for each FDW, because
it's just using the assembled connection string. To see if it's
assembling the connection string properly, we can unit test with
pg_conninfo_from_server().
