I have two versions of a db that I'd like to sync from a point-in-time
backup. One set of data is perfered over the other so the db on the
target system will need to be tossed.
Will pg_dump --clean fix up the target or do I need to dropdb instead?
The favored data is in under 8.2.1 and the target system is 8.2.6.
The doc for pg_dump --clean says it will drop db objects, not the db,
however it looks like it does, though the output order of events is
troubling. Is there a loop in the create/drop area?.
pgdump.test.dmp came from pg_dump -Fc :
$ strings pgdump.test.dmp
