Re: pg_restore

[Infor Gates <info_gates@xxxxxxxxx>]

Dear Tom

Thanks for your email.

You are right in saying table is already populated with the data. I was 
testing the pg_dump and pg_restore using pg_Admin III. 

I am having the impression that pg_restore would over-rides the "old"
data with the current one. Is my thinking wrong?  I have checked the
documentation but it was silence on this.  Does it means that whenever
I performed a pg_restore, I must first drop the "old" database.

I would be glad if you can help to clarify my understanding on 
pg_dump and pg_restore functions.

Thank you.

Considering that it's complaining at the very first line of COPY data,
I wonder whether you aren't restoring into a table that already contains
the data you want to load. pg_restore doesn't (by default) try to
delete data that's already present.
