[SQL] crypt function

[Francisco André Barbosa Neto]

Hi, my name is Andrew and I'm new to PostgreSQL.             Nowadays I'm using PostgreSQL version 7.02, and I have a table like this:   name varchar(8) password varchar(16)               How can I put the password into the table in a encrypted form, i try to do it:   INSERT INTO TABLE users VALUES ('test',crypt('passtest'));               But postgre returns an error telling that function crypt didn't exist!!               How can I fix this problem??               Thank you by your attention!!!
