Actually there is better place, the WalSndInit().
Just to make it easier for PeterE (or whichever committer picks this up)
I attached all the logical replication followup fix/polish patches:
0001 - Changes the libpqrcv_connect to use async libpq api so that it
won't get stuck forever in case of connect is stuck. This is preexisting
bug that also affects walreceiver but it's less visible there as there
is no SQL interface to initiate connection there.
0002 - Close replication connection when CREATE SUBSCRIPTION gets
canceled (otherwise walsender on the other side may stay in idle in
transaction state).
0003 - Fixes buffer initialization in walsender that I found when
testing the above two. This one should be back-patched to 9.4 since it's
broken since then.
0004 - Fixes the foreign key issue reported by Thom Brown and also adds
tests for FK and trigger handling.
0005 - Adds support for renaming publications and subscriptions.
All rebased on top of current master (90992e0).
