Reduce delay for last logicalrep feedback message when master goes idle.
The regression tests contain numerous cases where we do some activity on a
master server and then wait till the slave has ack'd flushing its copy of
that transaction. Because WAL flush on the slave is asynchronous to the
log
Shorten timeouts while waiting for logicalrep worker slot attach/detach.
When waiting for a logical replication worker process to start or stop,
we have to busy-wait until we see it add or remove itself from the
LogicalRepWorker slot in shared memory. Those loops were using a
one-second delay bet
Clean up misuse and nonuse of poll_query_until().
Several callers of PostgresNode::poll_query_until() neglected to check
for failure; I do not think that's optional. Also, rewrite one place
that had reinvented poll_query_until() for no very good reason.

Refine memory allocation in ICU conversions
The simple calculations done to estimate the size of the output buffers
for ucnv_fromUChars() and ucnv_toUChars() could overflow int32_t for
large strings. To avoid that, go the long way and run the function
first without an output buffer to get the cor

Update the documentation a bit to include that logical replication as
well as other and third-party replication clients can participate in
synchronous replication.
