Description: pg_dump -a does not respect referential dependencies
Details:
When using pg_dump to dump a database, the schema and data are arranged
within the dump so that it may be imported without violating referential
integrity.
When using the -a option to get a data-only dump, the data is ordered in the
dump alphabetically by table.
If a new schema is loaded into a fresh database, the output from the
data-only dump cannot be imported via \i in psql without manually editing
the dump file and reordering the inserts / copies such that dependent tables
have their data loaded before the tables that depend on them. This is
inconvenient at best.
Since the logic obviously exists within pg_dump already to arrange the data
in the correct order of reference dependencies, can this be added to the
code path for `pg_dump -a` as well? Or can another option be added that
specifies alphabetic vs. dependency order?
This would really cut down the time it takes to do schema upgrades on
projects that I work with.
Thanks
