That appears to be of limited use (i.e., it would only work for
functions, triggers and tables). pg_restore -L/--use_list is more
comprehensive. So the script would have to do something like the following:
$ pg_dump -Fc -Osx postgis > postgis.dump
$ pg_restore -l postgis.dump | sort -k4 > postgis.list
$ pg_restore -L postgis.list postgis.dump > postgis.sorted
Rinse and repeat on the second database and then diff the .sorted files. Tried it and although it doesn't completely
dothe trick it's much
better than diffing the plain text pg_dump outputs (3000+ diff lines vs.
less than 200 and about half of that are actual differences).
Thanks,
Joe
