This is really hackers stuff.

Some logic black holes... preliminarily public only.

A grep showed that only FK has handles public special, all other places
go through pgDatabase::GetSchemaPrefix.

The correct overall behaviour seems

- find the first schema in search_path that exists.
- If this is the schema in question, suppress it.
- (ignore all following schema names, this was the main problem)
- If schema = pg_catalog, suppress it.

Unfortunately, this search_path[i] = session_user is not absolutely
stable (schema or user name may change), but it should be stable enough.

Thoughts?
