Agreed. This is a repost/rewrite of the patch I have posted to the
pgadmin-support list a few days ago.

This version of the patch tries to address those issues in the following 

1. There is an additional checkbox in the Preferences tab of the Options 
dialog, labeled "Show data instead of properties for tables and views", 
placed as a subordinate of "Show object properties on double click" (I 
have stripped the "in treeview" part, since double click should also 
work in the Properties pane). The checkbox is disabled if its superior 
is disabled.

2. In the same tab, a parameter labeled "Maximum rows in data view" is 
introduced. It is used to limit the number of rows retrieved when 
constructing the data view/edit grid if greater than zero. The default 
value is set to 500, although it could be set to 0 (unlimited) to keep 
the behavior prior to its introduction.

The patch also arranges reading and writing of the new parameters from 
and to the configuration file.

The patch is against the beta1 source tree; I could re-sync it to the 
latest snapshot if needed.
