Thread: [COMMITTERS] pgsql: Use asynchronous connect API in libpqwalreceiver

Use asynchronous connect API in libpqwalreceiver

This makes the connection attempt from CREATE SUBSCRIPTION and from
WalReceiver interruptable by the user in case the libpq connection is
hanging.  The previous coding required immediate shutdown (SIGQUIT) of
PostgreSQL in that situation.
