Getting source code for database objects

[Artacus <artacus@xxxxxxxxxxx>]

On pgadmin, when you click on a table or function, you get the source 
code (DDL) to create that table or function.

I want to take that and check it into subversion so I have one file for 
each table, function, view, etc. My question is, how do you get that 
source code? I've been playing with pgadmin and wireshark trying to 
figure out what commands or queries it is using to no avail.
