Обсуждение: dependency ?

Hi,
  I was wondering if there is any way to use psql to list tables that
are dependent to a specific table.  Instead of going through every table
in my database and looking for foreign keys, can I somehow get an entire
list of these dependent tables?  Any help would be much appreciated, thanks!

pg_depend might help, although I think it'd be a multi-step link.

You could do this easily enough in the shell. For example, If I
wanted to find all tables that reference foo_table:

psql -U postgres database_name -c '\d *' | egrep "(Table |REFERENCES
foo_table)" | grep -B1 'REFERENCES foo_table' | grep 'Table ' | cut -
d '"' -f 2

should do the trick.
