Hi Jeff,
Insert SQL:
INSERT INTO test_indexes (bool_data , int_data , text_data ) VALUES (
(RANDOM() * 10)::INT % 2 = 0, RANDOM() * 10000, MD5((RANDOM() *
1000)::TEXT) );
pg_bench:
/usr/pgsql-11/bin/pgbench -Upostgres -f ${SQL} -n -c 60 -j 60 -T120 -p
${PORT}
Before each test run, I drop and recreate the table and indexes.
Cheers,
Paolo
