Dear hackers,

I found another failure related with the commit [1]. This is caused by missing
wait on the test code. Amit helped me for this analysis and fix.

# Analysis of the failure

The failure is that restored slot is two_phase = false, whereas the slot is
created as two_phase = true. This is because pg_upgrade was executed before all
tables are in ready state.

# How to fix

I think the test is not good. According to other subscription tests related with
2PC, they additionally wait until subtwophasestate becomes 'e'. It should be
added as well. PSA the patch.
