Use variable set by psql meta-command inside of DO block

Question

Here\'s what I would like to do:

\\set values foo,bar,baz

DO $$
DECLARE
    value  TEXT;
    values TEXT[] := string_to_array(:\'values\', \',\');
BEGIN
            


        

Answer 1

Was able to take advantage of this solution:

• Passing argument to a psql procedural script

Where I set the variable as such and retrieve it with current_setting()

\set values foo,bar,baz
SET vars.values TO :'values';

DO $$
DECLARE
    value  TEXT;
    values TEXT[] := string_to_array(current_setting('vars.values'), ',');
BEGIN
    FOREACH value IN ARRAY values LOOP
        RAISE NOTICE 'v: %', value;
    END LOOP;
END $$ LANGUAGE plpgsql
