Running the latest trunk build (g7ac0c60)

When pgAdmin displays the query output in a grid each column seems to be sized based on the header size and the value is truncated as needed. There is no indication that it's been truncated. This sometimes makes the result highly misleading and I've just spent 5-10 minutes scratching my head about why a function is returning such a strange result!

Here's what the output looked like: http://i48.tinypic.com/5fkdmp.png... but resizing the cell shows something very different: http://i47.tinypic.com/2ennsqv.png

I would suggest that pgAdmin:

1. Always truncate the end of the string, not the start
2. Show some indication that the string has been truncated, eg. append "..." or show some subtle overlay with a wavy line - as long as there's something.
3. For numeric types make the column wide enough to always show at least the part before the decimal point (or, for integer types, the entire number).

Items 1 and 2 seem enough.

Thanks for adding this. 1 and 2 together should be enough - 3 is a nice-to-have. I'd say that at least 1 should be high priority. It's not just a matter of convenience - the query output, as shown, is actually "incorrect". Yes, you can make it correct if you know how, but most people won't, especially if previous versions didn't do this.
