Hi, does anybody know what is wrong with pgbench in this case ?. Here is a
simple query to generate a random date in a interval time.sql:
(select timestamp '2005-09-01' + random() * ( timestamp '2006-03-01
00:00:00' - timestamp '2005-09-01 00:00:00' ));
query executed successfullly with psql
/usr/lib/postgresql/12/bin/psql -p 5432 -h localhost -d picp -U
postgres -f time.sql
BEGIN
?column?

psql (PostgreSQL) 12.3 (Ubuntu 12.3-1.pgdg20.04+1)
but look at what happen with pgbench
pgbench -c 2 -j 2 -M prepared --file time.sql -h localhost -d picp -U
postgres -p 5432
pghost: localhost pgport: 5432 nclients: 2 nxacts: 10 dbName: picp

I don't know why pgbench use timestamp: «2006-03-01 00$1$2» instead of
timestamp '2006-03-01 00:00:00'
