问题
I have created some user defined aggregate functions. However, I cannot see a way to export them in pgAdmin. Or any other way.
I can see the underlying functions, but not the CREATE AGGREGATE definitions.
SquirrelSQL doesn't show anything useful either!

Most probably you need to enable the display of aggregates in your Options:
File -> Options -> Browser -> Display
After refreshing the view you get a separate node Aggregates in the object browser:
The reverse engineered CREATE script for the selected aggregate is displayed to the right in the SQL pane.
