Well, grep is not going to work too well anymore, but extracting a specific field from an entry is going to be beyond the competence of simple grep/sed tools anyway if we allow column default substitutions. I think a fairer question is "can you do that in a one-liner Perl script", which seems like it might be achievable given an appropriate choice of data markup language. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
