Jason Petersen 8274680f5b Attempt to address planner context crashes 
Both of these are a bit of a shot in the dark. In one case, we noticed
a stack trace where a caller received a null pointer and attempted to
dereference the memory context field (at 0x010). In the other, I saw
that any error thrown from within AdjustParseTree could keep the stack
from being cleaned up (presumably if we push we should always pop).

Both stack traces were collected during times of high memory pressure
and locally reproducing the problem locally or otherwise has been very
tricky (i.e. it hasn't been reproduced reliably at all).

Hadi Moshayedi 547c9d3301 Keep track of cached entries in case of interruption. (#2433) 
* Keep track of cached entries in case of interruption.

Previously we set DistTableCacheEntry->sortedShardIntervalArray
and DistTableCacheEntry->shardIntervalArrayLength after we entered
all related shard entries into DistShardCacheHash. The drawback was
that if populating DistShardCacheHash was interrupted,
ResetDistTableCacheEntry() didn't see the shard hash entries created,
so was unable to clean them up.

This patch fixes that by setting sortedShardIntervalArray earlier,
and incrementing shardIntervalArrayLength as we enter shards into
the cache.

Murat Tuncer 25673600d3 Fix memory leak in FinishRemoteTransactionPrepare 2018-11-14 20:49:30 +03:00
Onder Kalaci c95b13863b Prevent overflow of memory accesses during deadlock detection 
In the distributed deadlock detection design, we concluded that prepared transactions
cannot be part of a distributed deadlock. The idea is that (a) when the transaction
is prepared it already acquires all the locks, so cannot be part of a deadlock
(b) even if some other processes blocked on the prepared transaction,  prepared transactions
 would eventually be committed (or rollbacked) and the system will continue operating.

With the above in mind, we probably had a mistake in terms of memory allocations. For each
backend initialized, we keep a `BackendData` struct. The bug we've introduced is that, we
assumed there would only be `MaxBackend` number of backends. However, `MaxBackends` doesn't
include the prepared transactions and axuliary processes. When you check Postgres' InitProcGlobal`
you'd see that `TotalProcs = MaxBackends + NUM_AUXILIARY_PROCS + max_prepared_xacts;`

This commit aligns with total procs processed with that.

Murat Tuncer f20258ef10 Expand count distinct support 
We can now support more complex count distinct operations by
pulling necessary columns to coordinator and evalutating the
aggreage at coordinator.

It supports broad range of expression with the restriction that
the expression must contain a column.
