Adrian, Thank you for your response. I would note that the original dump archive created by pg_dump included all schemas and that I only intend to restore a schema from it that is self contained, or a group of related tables from it.
I just tried that here and succeeded. I did a pg_dump and then restored only the public schema which in this database is self contained. I did get the HINT because I used the -c switch and it tried to drop the public schema and there where existing objects dependent on it. The restore threw the HINT and a subsequent ERROR over trying to CREATE SCHEMA public where it already existed, but it completed the restore.
I acknowledge the dangers inherent in selective restoration, it just seems that a couple of additional options ( disable constraints, drop cascade ) to pg_restore would improve this utility to users who have put some thought into laying out the database design and failure cases from which they would like to recover. To have a pg_restore selective restoration options, (-n, -t ), and have it fail simply because there are foreign keys amongst the tables within that schema seems like to much protection or protection that I would at least like to have option to over-ride.
We will probably need to see more detail on why that failed in your case because I did not see that in mine. Another way to influence the outcome is to use the -l and -L options to pg_restore. -l returns the -Fc dump file table of contents(TOC) as a list. You can redirect that to a file and in that file comment out(using ;) items and rearrange the order of the TOC to suit your needs. Then you use pg_restore with the -L option to feed it the edited TOC.

It may well be that I could shoot myself in the foot, but I'd still like to own the firearm :+) Regards Dave Day
