The new _overflow functions have buggy comments:
/*
* If a - b overflows, return true, otherwise store the result of a + b into

Start a separate test suite for plpgsql
The plpgsql.sql test file in the main regression tests is now by far the
largest after numeric_big, making editing and managing the test cases
very cumbersome. The other PLs have their own test suites split up into
smaller files by topic. It would be nice

Rethink MemoryContext creation to improve performance.
This patch makes a number of interrelated changes to reduce the overhead
involved in creating/deleting memory contexts. The key ideas are:
* Include the AllocSetContext header of an aset.c context in its first
malloc request, rather than all

This reverts commit 778e78ae9fa51e58f41cbdc72b293291d02d8984. Per
further discussion, that doesn't seem to be the best possible fix.

Fix parallel index scan hang with deleted or half-dead pages.
The previous coding forgot to release the scan before seizing
it again, leading to a lockup.

Add defenses against pre-crash files to BufFileOpenShared().
Crash restarts currently don't clean up temporary files, as a debugging aid.
If a left-over file happens to have the same name as a segment file we're
trying to create, we'll just truncate and reuse it, but there is a problem:

Allow executor nodes to change their ExecProcNode function.
In order for executor nodes to be able to change their ExecProcNode function
after ExecInitNode() has finished, provide ExecSetExecProcNode(). This allows
any wrappers functions that only execProcnode.c knows about to be reinstalled.

Add pg_attribute_always_inline.
Sometimes it is useful to be able to insist that the compiler inline a
function that its normal cost analysis would not normally choose to inline.
This can be useful for instantiating different variants of a function that
remove branches of code by constant folding.
