Thread: Incremental Dump

Is there a proceedure to allow one to compare the database structure of a
deployed database against a developmenmt database to note any structural
change in one or more tables?

I'd try pg_dump -s (schema only) and diff the two dumps.  You might have
to do some fooling around if objects were created in different orders in
the two databases, though, since that would affect the dump order.

Well Tom, the two databases are production and development. The table create
sequence should be the same.

Thanks for the insight !!

I'd also remove all comments:

pg_dump -s dbname |egrep -v "^\-\-"
