Обсуждение: How determine a Views dependents

Fellow Postgressors,
    I took over an existing PG 8.0 database running on Windows XP. I need to
update a view so I know I need to drop the existing view and all the objects
that depend on it.
    The DB is large enough that I can't just look through it with PGAdmin. In
an organized way, how can I find out what those dependents are?
    If I need to use pg_depend, I could use some help in how to do that.
    Thanks!

Have you looked at the output of \d <view name> in psql?

The traditional way is

    drop view victim restrict;
    ... read the error message ...
