pgsql: In LDAP test, restart after pg_hba.conf changes
In LDAP test, restart after pg_hba.conf changes
Instead of issuing a reload after pg_hba.conf changes between test
cases, run a full restart. With a reload, an error in the new
pg_hba.conf is ignored and the tests will continue to run with the old
settings, invalidating the subsequent test cases. With a restart, a
faulty pg_hba.conf will lead to the test being aborted, which is what
we'd rather want.
