commit 8a05756a702051d55a35ec3f4953f381f977b53a
Author: Pavan Deolasee <pav...@gm...>

Implement support for CREATE TABLE AS, SELECT INTO and INSERT INTO
statements. We start by fixing the INSERT INTO support. For every result
relation, we now build a corresponding RemoteQuery node so that the
inserts can be carried out at the remote datanodes. Subsequently, at
the coordinator at execution time, instead of inserting the resulting tuples
in a local heap, we invoke remote execution and insert the rows in the
remote datanodes. This works nicely even for prepared queries, multiple
values clause for insert as well as any other mechanism of generating
tuples.
We use this infrastructure to then support CREATE TABLE AS SELECT (CTAS).
The query is transformed into a CREATE TABLE statement followed by
INSERT INTO statement and then run through normal planning/execution.
There are many regression cases that need fixing because these statements
now work correctly. This patch fixes many of them. Few might still be
failing, but they seem unrelated to the work itself and might be a
side-effect. We will fix them once this patch gets in.

commit a53dd68ce6ab8a66ae7b4f7487b3b1aa78423894

This commit allows GTM-Standby to connect to GTM anytime. Without this patch,
GTM-Standby must connect to GTM before any clients are connected. This patch
eliminates this restriction.
In this patch, I used thr_lock RW lock which was not used so far. When GTM-Standby
connects to GTM, GTM recognizes that this is another GTM (then, standby) and
registers this as another GTM, which will be used later by main thread and
worker thread.
For running worker thread to begin backup to standby, it must connect to it.
Before backup from each running worker threads begin, all the existing transaction
status and sequence status must be backed up. For this purpose, when GTM-standby
connects to GTM, it issues new message MSG_BEGIN_BACKUP. When GTM receives this,
GTM locks all the worker thread to make status static. Then GTM-Standby issues
commands to backup everything. When backup is done, GTM-Standby issues
MSG_END_BACKUP, whcih release the lock of each worker thread.
When the lock is released, each worker thread checks if there're new GTM-Standby
connected. If so, each worker thread connects to GTM-Standby and begin backup
of each worker thread.
There're no update in the document.
