List stored functions that reference a table in PostgreSQL

Question

Just a quick and simple question: in PostgreSQL, how do you list the names of all stored functions/stored procedures using a table using just a SELECT statement, if possible

Answer 1

You can use the standard information_schema schema to get metadata about your database (it's in the SQL standard, so it should work the same way in different database systems). In this case you want information_schema.routines.
