SQL features...

There seems to be a few SQL compatibility issues in Postgres that are
making it difficult for me to convert from Interbase. They are:

Support for foreign keys
Cascading a deletion across a referenced table or tables using a foreign
key

Does anyone know when these feature might be implemented?

Also: Is libpg a shared library? Can I write a client program say on a
FreeBSD
box that links to this library and calls a remote
Postgres db server running on a Linux box?

Thanks
