You are right. That's where encryption comes into play.

A rule of thumb in job-seeking is when you don't have experience, your

Lyndon,
pg_dump equals export in Oracle. Actually pg_dump all = export full=y.
It's just a syntax difference. And if you have a full export all you need to to
recreate the database is create the system tablespace. And yes it is easy with
Oracle, if you keep it simple.

Hi Lyndon
hsql == HypersonicSQL. It's a pure Java, lightweight database
server. Not
suitable for large amounts of data, more the way to go if you're
looking for
an SQL database to embed into your Java app.
I thought we were talking about Oracle
for the validity of the statements and comments
given above.

Well no. Since you are comparing Postgresql with Oracle, why

And is postgresql scalable compare to Oracle? Can it handle my

Hi
I just posted that as reply to your question about hsql (what is it

I misunderstood your previous answer. I thought you were talking about
an Oracle command that can export a plain text sql script like pg_dump
that's why I asked.
Thank you.

True, an export file is peculiar to Oracle. The difference between a
commercial database and an open source one. IBM and MicroSludge do the same.
The functional purpose though is the same.
