Assunto: [SQL] Finding all tables that have foreign keys referencing a table

Hi.
I see the last comment here suggests a solution for $subject:
http://www.postgresql.org/docs/8.1/interactive/ddl-constraints.html

But it turns out it assumes constraint_name is unique, which is not the case. It is only unique pr. table. In other words, it produces a lot of false results.

I'm trying to make a function which finds all my old "$1" constraints and replaces those names with proper names (_fkey).

So - anybody who knows a good solution for how to find all tables with constraint-names that have foreign keys referencing a table's particluar colum?
