Re: Postgres 13 signal 11: Segmentation fault tested on 2 independent machines

cast to text those 2 columns helped:

sut.schemaname::TEXT, sut.relname::TEXT

so this function doesn't cause segmentation fault

CREATE OR REPLACE FUNCTION vacuum_dead_size(i_now timestamp with time zone,
OUT schemaname TEXT, OUT relname TEXT, OUT total_bytes NUMERIC, OUT
dead_tup_size NUMERIC)
RETURNS SETOF RECORD
AS $$

    WITH closest_metric_stat_user_tables AS (
        SELECT now FROM stat_user_tables ORDER BY abs(now-$1) LIMIT 1
    ), closest_metric_table_sizes AS (
        SELECT now FROM table_sizes ORDER BY abs(now - $1) LIMIT 1
    )
SELECT sut.schemaname::TEXT, sut.relname::TEXT, ts.total_bytes, 1::numeric
FROM stat_user_tables sut
         LEFT JOIN table_sizes ts ON ts.table_name = sut.relname AND
ts.table_schema = sut.schemaname
    WHERE ts.now = (SELECT now FROM closest_metric_table_sizes) AND sut.now
= (SELECT now FROM closest_metric_stat_user_tables)
ORDER BY 1;
$$ LANGUAGE SQL;
