Try this
select table_schema, table_name
from information_schema.columns
where table_schema not in
('information_schema','pg_catalog')
and column_name = '?'

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?
