PostgreSql pass array argument in WHERE NOT - postgresql

Question

I have a sql function that creates a materialized view:
CREATE FUNCTION reports_mt_views(exclude_ids int[]) RETURNS void AS
$BODY$
BEGIN
EXECUTE 'CREATE MATERIALIZED VIEW tx_materialized AS
SELECT tx.transaccion_id AS tx_transaccion_id,
...
WHERE creation_date > (current_date - interval '' 3 month '')
AND (account_id <> ALL (' || $1 || '))'
RETURN;
END;
$BODY$ LANGUAGE plpgsql STRICT;
I also tried as:
AND account_id NOT IN ' || $1|| ')'
But it does not work. When I execute:
SELECT reports_mt_views(ARRAY [1,2,8,538524]);
I have this error:
ERROR: operator does not exist: text || integer[]
LINE 171: AND (account_id <> ALL (' || $1 || '))'
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
There is not a problem with the array itself I tested it with a FOR loop and works. But into the condition it does not. What I have missed here?

Answer 1

The solution was to concanate the array as a text then it can be readby the clause where not in.
CREATE OR REPLACE FUNCTION pps.reports_mt_views(exclude_ids integer[])
...
DECLARE
in_accounts ALIAS FOR $1;
out_accounts TEXT;
BEGIN
out_accounts := in_accounts;
out_accounts := trim(leading '{' FROM out_accounts);
out_accounts := trim(trailing '}' FROM out_accounts);
And it can be used as:
WHERE (orden.cuenta_id NOT IN (' || out_accounts || '))
