I'm sorry if this is has been discussed, but I tried to find the answer
in the archives and failed, so...
How do I find all the rows in other tables that reference a specific row
in another table? I'm only trying to find rows that are in tables where
there is a Foreign Key referencing the primary key of the table in question.
Example:
Table People has a primary key of people_id
There are say 20 tables that have foreign keys referencing people.people_id
How do I find all the rows in all of those 20 tables that reference a
particular person in the people table?
Thank you in advance,
Matthew O'Connor

pg_catalog.pg_constraint has that info.
