> This issue was revealed by using SimEx on a debug build, with gp_simex_class
> set to 1 (cancel query).
> The second time a query is run in simex mode, this error is seen:
> {noformat}
> FATAL: terminating connection due to administrator command
> server closed the connection unexpectedly
> This probably means the server terminated abnormally
> before or while processing the request.
> {noformat}
> Repro:
> Setup:
> {noformat}
> compile with configure parameter --enable-testutils
> hawq config -c gp_simex_init -v on
> hawq config -c gp_simex_class -v 1
> hawq restart cluster
> {noformat}
> Run the attached inject script with the attached prepare_simple.sql and
> test_simple.sql files.
