I think what you're looking for is the equivalent to oracles external
tables which invoke sqlldr every time you access them in the
background. No such animal in the pg universe that I know of.

Removed pgsql-jdbc from cc list. You're still better off sending to
the right list. And so are we. The general list has a much larger
readership than jdbc, and it's far more likely you'll run into someone
with oracle experience here who knows about the external table format,
etc...
