I want to get all the dependencies of a table, I know how to get the index list using sql, but I don't know how to get the list of objects who using a function, for example:
CREATE OR REPLACE FUNCTION reverse_last_64(TEXT) RETURNS TEXT AS $$ SELECT array_to_string( ARRAY ( SELECT substring($1, s.i,1) FROM generate_series(length($1), greatest(length($1) - 64 + 1, 1), -1) AS s(i) ), ''); $$ LANGUAGE SQL IMMUTABLE" CREATE TABLE Test2(id BIGSERIAL PRIMARY KEY, name varchar(100)) CREATE INDEX idx_test2_name ON test2(reverse_last_64(name) varchar_pattern_ops) drop function reverse_last_64(TEXT) ; will show ERROR: cannot drop function reverse_last_64(text) because other objects depend on it DETAIL: index idx_test2_name depends on function reverse_last_64(text) HINT: Use DROP ... CASCADE to drop the dependent objects too. what I want to get is the list of index(or maybe other function) which using the function using sql. anyone can help me? thanks -- Xu Wei Email: eaglein...@gmail.com
