Default value for char/varchar columns is not quoted automaticaly

Default value for char/varchar columns is not quoted automaticaly when 
creating a table or adding new column to existing table.

-- PGAdmin --

version: PGAdmin III version 1.0.0
OS:      Windows XP Professional SP1

-- postgres --

Postgres: 7.3.4 on i686-pc-linux-gnu
OS:       RedHat Linux 9

- Steps to reproduce --

1.Add a new column of (var)char type to existing table with column's 
default value "test value" (withou the quotes)

-- Current result --

Column is not added (parse error)

-- Expected result --

New column is added

-- Notes --

Same behavior is when creating the table.

If this behavior is "by design" and the user required to enter the 
quotes manualy, take it please just as a feature request to automaticaly 
quote character-type defaults

Thank you for creating great tool as PGAdmin is.
Hope this will help you to improve PGAdmin.
