In response to backing up the data from a single table?  (stan <stanb@panix.com>)

Hi Stan,

My development methodology is to create scripts that init the db, and load
test data, as I make changes.

Now, I am starting to move toward a test instance with real data. The end
user has provided "real" test data, n spreadsheets. I have the inputing of
data from these working OK. (takes a bit of hand work). What I would like
to do, is  continue to init the "test" database. To make that easy, I would
like to be able to "export" individual tables, so I can use the scripts to
reload them. I prefer not to have to convert these to my load script
format.

Is there a way to "export" a single table, that can be easily re
"imported"?

It may be a strange suggestion but did you consider containers like Docker? It's been a great help on a 100GB+ test database. Successful changes were committed, failed changes were rolled back creating a new instance based on the same image (with data preloaded). It takes seconds to do a rollback.
