I used the database "regression" that pg_regress leaves behind when you
remove the --temp-install from it's default invocation through make
check. Sorry about not being explicit about that.
So, dropping one of the queries into src/test/regress/sql/smith.sql and
invoking
make check EXTRA_TESTS=smith
was all that was needed to integrate them. I was then able to perform
"git bisect run" on this command. Er, plus consing the expected output
file.
I'm using the regression db a lot when hacking on sqlsmith, as it
contains much more nasty things than your average database.
