Fix pgpool child process segfault when ALWAYS_MASTER is on.
If following conditions are all met pgpool child segfaults:
1) Streaming replication mode.
2) fail_over_on_backend_error is off.
3) ALWAYS_MASTER flag is set to the master (writer) node.
4) pgpool_status file indicates that the node mentioned in #3 is in
down status.
What happens here is,
1) find_primary_node() returns node id 0 without checking the status
of node 0 since ALWAYS_MASTER is set. It's remembered as the
primary node id. The node id is stored in Req_info->primary_node_id.
2) The connection to backend 0 is not created since pgpool_status says
it's in down status.
3) upon starting of session, select_load_balancing_node () is called
and it tries to determine the database name from client's start up
packet.
4) Since MASTER_CONNECTION macro points to the PRIMARY_NODE,
MASTER_CONNECTION(ses->backend) is NULL and it results in a segfault.
The fix is, to change PRIMARY_NODE_ID macro so that it returns
REAL_MASTER_NODE_ID (that is the youngest node id which is alive) if
the node id in Req_info->primary_node_id is in down status. This can
be checked using VALID_BACKEND_RAW macro.
VALID_BACKEND macro cannot be used here because it calls
pool_is_node_to_be_sent_in_current_query() inside. Problem is, when a
query is about to processed, pool_is_query_in_progress() is already
set but pool_is_node_to_be_sent() could return false because
where_to_send member in the query context may not be is set yet

If an erroneous query is sent to primary and the next query requires a
catalog cache look up, Pgpool-II hangs in do_query(). do_query()
calls pool_push_pending_data() which expects response from backend
because it internally send CLOSE message and flush message. In normal

since the backend is in error state, any command including CLOSE sent
by pool_push_pending_data() is ignored.
This only happens if the erroneous query is sent to primary and

Fix is, let pool_push_pending_data() detect an error message and set
ignore_till_sync flag. This will let do_query() just pops the data
pushed in pool_push_pending_data(). pool_search_relcache(), caller of
do_query(), in turn checks the flag. If the flag is set, do not cache

Fix pgpool start message printed multiple times.
When an exception occurs in the main loop, longjmp() gets called and
the variable "first" restored to the initial value. This make the
pgpool start message printed multiple times. This is harmless but
confusing. To fix that, add "volatile" qualifier so that the variable
is on the stack, rather than on a register.
Fix suggested by Muhammad Usama.

Watchdog process should make sure that it's Master/coordinator status is
synchronised across the watchdog cluster before accepting the failover requests.
This will make sure that no other node is processing the same failover request.

Fixing an issue in the handling of pg_terminate_backend()
In some cases pg_terminate_backend() can cause failover even when
the call is properly issued through Pgpool-II.
This problem is, we do not set of the swallow_termination flag when the
pg_terminate_backend refers to the backend connection of the child
process on which the pg_terminate_backend() was issued.
This was due to the wrong assumption, that we always get the proper
socket close indication when backend to terminate is the same on which
pg_terminate_backend() is issued, Apparently this is not the case,
and PostgreSQL backend can still get abruptly killed even when it is
asked to terminate itself, And this abrupt termination of the connection
makes the Pgpool-II to consider it as a backend failure.
The solution to this is to always set the swallow_termination, even when the
pg_terminate_backend is referring to the local backend connection.
