Waiting for 9.6 – Add CASCADE support for CREATE EXTENSION.

On 3rd of October, Andres Freund committed patch:

Add CASCADE support for CREATE EXTENSION.
 
Without CASCADE, if an extension has an unfullfilled dependency on
another extension, CREATE EXTENSION ERRORs out with "required extension
... is not installed". That is annoying, especially when that dependency
is an implementation detail of the extension, rather than something the
extension's user can make sense of.
 
In addition to CASCADE this also includes a small set of regression
tests around CREATE EXTENSION.

Waiting for 9.6 – Allow per-tablespace effective_io_concurrency

On 8th of September, Alvaro Herrera committed patch:

Allow per-tablespace effective_io_concurrency
 
Per discussion, nowadays it is possible to have tablespaces that have
wildly different I/O characteristics from others.  Setting different
effective_io_concurrency parameters for those has been measured to
improve performance.

Waiting for 9.6 – Allow usage of huge maintenance_work_mem for GIN build.

On 2nd of September, Teodor Sigaev committed patch:

Allow usage of huge maintenance_work_mem for GIN build.
 
Currently, in-memory posting list during GIN build process is limited 1GB
because of using repalloc. The patch replaces call of repalloc to repalloc_huge.
It increases limit of posting list from 180 millions
(1GB / sizeof(ItemPointerData)) to 4 billions limited by maxcount/count fields
in GinEntryAccumulator and subsequent calls. Check added.
 
Also, fix accounting of allocatedMemory during build to prevent integer
overflow with maintenance_work_mem > 4GB.
