please remove pgsql warning on fetch_row - includes diff

Hi! The PostgreSQL module issues a warning when trying to fetch a row with an invalid rownumber. pg_fetch_row also returns false. I would ask if someone could remove the warning that is issued. The docs says the function returns false, this should be enough, I think. I would really like to construct a while-loop while (pg_fetch_row()) { ... } In fact, in the dbx-module I am doing exactly that, and the postgresql addition generates the warning even though the loop is ended successfully... To make it easier, I attached a diff that removes said warning. I'm not really sure if this is how a patch is submitted (do you need a diff for that?), but if I'm doing something wrong maybe anyone can show me how it's done. Cheerio, Marc. <<pgsql.c.diff>>
