Re: best method to copy data across databases

Many thanks Tony and Tom,

since this was a "one time" process speed wasn't an issue...
I just did a plain pg_dump with insert and explicit column names in
the dump, then used vi to rename the columns and get rid of some of
them...
non very scientific but it worked :)

cheers.
