PL/pgSQL SELECT into an array

Here’s my function declaration and part of the body:

CREATE OR REPLACE FUNCTION access_update()
RETURNS void AS $$
DECLARE team_ids bigint[];
BEGIN
    SELECT INTO team_ids "team_id" FROM "tmp_team_list";

    UPDATE "team_prsnl"
    SET "updt_dt_tm" = NOW(), "last_access_dt_tm" = NOW()
    WHERE "team_id" IN team_ids;
END; $$ LANGUAGE plpgsql;

I want team_ids to be an array of ints that I can then use in the UPDATE statement. This function give me errors like this:

psql:functions.sql:62: ERROR:  syntax error at or near "team_ids"
LINE 13:  AND "team_id" IN team_ids;

Answer

Faster and simpler with a FROM clause in your UPDATE statement:

UPDATE team_prsnl p
SET    updt_dt_tm = now()
     , last_access_dt_tm = now()
FROM   tmp_team_list t
WHERE  p.team_id = t.team_id;

That aside, while operating with an array, the WHERE clause would have to be:

WHERE p.team_id = ANY (team_ids)

The IN construct works with lists or sets, not with arrays. See:
