Re: paertially restoring a DB

Hi,

What you are trying to do should be possible as far as I know.

Did you use the custom format for your dump (pg_dump -Fc)? Try extracting a 
list of contents of the dump (pg_restore --list) option and check that for 
anything that might be causing you to lose that table. Comment out any 
offending lines and restore using the --use-list option.

If you used the custom format you have a lot of options for extracting 
individual table data and stuff like that.

Good luck,
Iain
