I would have to suggest JUMP as a possibility. It doesn't allow in-table 
editing (yet) but you can suck out a table and edit it, then save it back to a 
new table (with the postgis plugin). This won't work very well if your table is 
too large to fit all in memory at once... eventually there will probably a 
better postgis plugin with support for in-table editing.
