I run an xp program in vmware that uses a postgresql db.  I want to back
up this db from linux.  The cmd I was given to backup the db from within
xp is:
   pg_dump.exe -i -h <server> -p <port> -U <user> -F c -v -f <filename> <DB Name>

I'm trying to  accomplish the following:
GRANT all ON friends TO www-data;
however the - sign in www-data seems to be a problem, how should I
escape it correctly?

 is there any way to revice value of autoincrement column.
lets suppose that we have to tables:
1. document (id serial)
2. document_positions( id serial, document_id)
