Tom Lane	5fd386bb31	Get rid of postgres_fdw's assumption that remote type OIDs match ours. The only place we depended on that was in sending numeric type OIDs in PQexecParams; but we can replace that usage with explicitly casting each Param symbol in the query string, so that the types are specified to the remote by name not OID. This makes no immediate difference but will be essential if we ever hope to support use of non-builtin types.	13 years ago
Tom Lane	6d06049493	Adjust postgres_fdw's search path handling. Set the remote session's search path to exactly "pg_catalog" at session start, then schema-qualify only names that aren't in that schema. This greatly reduces clutter in the generated SQL commands, as seen in the regression test changes. Per discussion. Also, rethink use of FirstNormalObjectId as the "built-in object" cutoff --- FirstBootstrapObjectId is safer, since the former will accept objects in information_schema for instance.	13 years ago
Tom Lane	d0d75c4022	Add postgres_fdw contrib module. There's still a lot of room for improvement, but it basically works, and we need this to be present before we can do anything much with the writable-foreign-tables patch. So let's commit it and get on with testing. Shigeru Hanada, reviewed by KaiGai Kohei and Tom Lane	13 years ago

Get rid of postgres_fdw's assumption that remote type OIDs match ours.

The only place we depended on that was in sending numeric type OIDs in
PQexecParams; but we can replace that usage with explicitly casting
each Param symbol in the query string, so that the types are specified
to the remote by name not OID.  This makes no immediate difference but
will be essential if we ever hope to support use of non-builtin types.

start, then schema-qualify only names that aren't in that schema.  This
greatly reduces clutter in the generated SQL commands, as seen in the
regression test changes.  Per discussion.

Also, rethink use of FirstNormalObjectId as the "built-in object" cutoff
--- FirstBootstrapObjectId is safer, since the former will accept
objects in information_schema for instance.

There's still a lot of room for improvement, but it basically works,
