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

If you are using psql, try \df

From the man page:

Tip
To look up functions taking arguments or returning values of a specific type, use your pager's search capability to scroll through the \df output.

Running \set ECHO_HIDDEN will reveal what \df is running behind the scenes.
