That has potential. However, in some instances the object I'm
refactoring will end up having dependencies, for instance for the case
of views oftentimes I will have to do the drop/create for it and all
dependent objects. In those situations, generating scripts from the
pg_restore output is very convenient, since it tells me all the
dependencies and I can adjust the listfile contents to get them all and
in the correct order.
At this point I'm thinking to wrap the pg_restore invocation in a script
that includes piping through sed to transform the create statements.
I would have thought that the functionality in PgAdmin and the command
line utilities would rely on the same underlying source code and so
support the same functionality. Alas.
