Hello,
Is there a feature in Postgres where we can perform a query that selects
all tables that reference a primary key?
For example if I have three tables b.main(k integer primary key, v
integer),
b.foo(k integer
primary key references b.main(k), v timestamp with time zone),
b.bar(k integer
primary key references b.main(k), v timestamp with time zone)
Currently I'm using a cascading type query but was curious if there was
way to perform queries using referenced keys.
The psuedo code would look something like: select all tables where
b.main.k is referenced.
The results would be rows/columns from b.main,b.foo,and b.bar.
I've searched through the Postgresql documentation, but didn't find the
solution I was looking for. Is there way to do this?
I posted this question on stackoverflow as well but received minimal
feedback, so thought I would try here as well. If interested the link is
http://stackoverflow.com/questions/12808963/select-all-referenced-tables
Thanks,
Robert Wing
