Reduce Postgres logs noise on regression tests

For each regression database created we execute the
test/sql/utils/testsupport.sql to setup some test stuff before actually
run the tests. Once we config Postgres to emit log for all executed
statements we create a log of noise on logs about this setup SQL script.

Change it to run the setup SQL script on the `template1` database so all
new created databases will contain all the necessary objects for run the
tests.
