Merge pull request #1816 from citusdata/fix_reference_regression 
Relax the checks for ensuring distribution columns in the target list
 2017-11-21 16:07:14 +03:00
Onder Kalaci d558ebb923 Relax the checks on ensuring distribution columns for target entries 
With this commit, we allow pushing down subqueries with only
reference tables where GROUP BY or DISTINCT clause or Window
functions include only columns from reference tables.

Andres Freund d063658d6d Protect some initializations from being called during backend startup. 
On EXEC_BACKEND builds these functions shouldn't be called at every
backend start.

Brian Cloutier d267e0f9fa EXEC_BACKEND: don't put pointers to shared hashes into shared memory 
Store pointers to shared hashes in process-local variables. Previously
pointers to shared hashes were put into shared memory. This causes
problems on EXEC_BACKEND because everybody calls execve and receives a
brand new address space; the shared hash will be in a different place
for every backend. (normally we call fork, which gives you a copy of the
address space, so these pointers remain constant)

Merge pull request #1809 from citusdata/get_rid_of_false_positives 
Get rid of some of the false positive distributed deadlocks
 2017-11-15 16:13:57 +03:00
Onder Kalaci 5bea95009b Skip autovacuum processes for distributed deadlock detection 
Autovacuum process cancels itself if any modification starts
on the table in order to avoid blocking your regular Postgres
sessions. That's normal and expected. Thus, any locks held by
autovacuum process cannot involve in a distributed deadlock
since it'll be released if needed.
 2017-11-15 14:32:16 +02:00
Onder Kalaci c65c153a46 Skip speculative locks for distributed deadlock detection 
These locks are held for a very short duration time and cannot
contribute to a deadlock. Speculative locks are used by Postgres
for internal notification mechanism among transactions.

Burak Yucesoy 17229ed7bd Fix attaching partition to a distributed table in schema 
While attaching a partition to a distributed table in schema, we mistakenly
used unqualified name to find partitioned table's oid. This caused problems
while using partitioned tables with schemas. We are fixing this issue in
this PR.

Merge pull request #1777 from citusdata/skip_page_locks 
Skip page-level locks for distributed deadlock detection
 2017-11-09 13:01:21 +03:00
Onder Kalaci 94921a2be1 Skip page-level locks on distributed deadlock detection 
Short-term share/exclusive page-level locks are used for
read/write access. Locks are released immediately after
each index row is fetched or inserted.

Since those locks may not lead to any deadlocks, it's safe
to ignore them in the distributed deadlock detection.
