Not to argue since I'm pretty novice with pgAdmin, but every time I open a table with "View Top 100 Rows" the filter/sort options are already set to PRIMARY KEY Ascending. Can we offer the reverse behavior? Matt matt@luggagepros.com

I commited it tonight. See http://git.postgresql.org/gitweb?p=pgadmin3.git;a=commit;h=527e2972bfff8cb8f16db6155980760c6810496b for the actual patch. It adds a "View Last X lines" menu item everywhere there is a "View Top X lines". Thanks for the request, Matt. And thanks for the patch, Steffen. -- Guillaume http://www.postgresql.fr http://dalibo.com
