The string "% of total" was marked by xgettext to be a c-format, but it

Compute the column widths of the final display dynamically based on the

Our documentation hasn't really caught up with the fact that
non-exclusive backups can now be taken using pg_start_backup and
pg_stop_backup even on standbys. Update, also correcting some
errors introduced by 52f8a59dd953c6820baf153e97cf07d31b8ac1d6.
Updates to the 9.6 documentation are needed as well, but that
will need a separate patch as some things are different on that
version.

Minor improvements for commit 1f6d515a6. We do not need the (rather
expensive) test for SRFs in the targetlist, because since v10 any
such SRFs would appear in separate ProjectSet nodes. Also, make the
code look more like the existing cases by turning it into a simple
recursion --- the argument that there might be some performance
benefit to contorting the code seems unfounded to me, especially since
any good compiler should turn the tail-recursion into iteration anyway.

Commit 8c0d7bafad36434cb08ac2c78e69ae72c194ca20 introduced dshash with hash
and compare functions like DynaHash's, and also variants that take a user
data pointer instead of size. Simplify the interface by merging them into
a single pair of function pointer types that take both size and a user data
pointer.
Since it is anticipated that memcmp and tag_hash behavior will be a common
requirement, provide wrapper functions dshash_memcmp and dshash_memhash that
conform to the new function types.

The test case added by commit 1f6d515a6 fails on buildfarm members that
have force_parallel_mode turned on, because we currently don't report sort
performance details from worker processes back to the master. To fix that,
just make the test table be temp rather than regular; that's a good idea
anyway to forestall any possible interference from auto-analyze.
(The restriction that workers can't access temp tables might go away
someday, but almost certainly not before the other thing gets fixed.)
Also, improve the test so that we retain as much as possible of the
EXPLAIN ANALYZE output. This aids debugging failures, and might also
expose problems that the preceding version masked.

Add general purpose chaining hash tables for DSA memory. Unlike
DynaHash in shared memory mode, these hash tables can grow as
required, and cope with being mapped into different addresses in
different backends.
There is a wide range of potential users for such a hash table, though
it's very likely the interface will need to evolve as we come to
understand the needs of different kinds of users. E.g support for
iterators and incremental resizing is planned for later commits and
the details of the callback signatures are likely to change.

Previously, tuple descriptors were stored in chains keyed by a fixed size
array of OIDs. That meant there were effectively two levels of collision
chain -- one inside and one outside the hash table. Instead, let dynahash.c
look after conflicts for us by supplying a proper hash and equal function
pair.
This is a nice cleanup on its own, but also simplifies followup
changes allowing blessed TupleDescs to be shared between backends
participating in parallel query.

TupleDesc's attributes were already stored in contiguous memory after the
struct. Go one step further and get rid of the array of pointers to
attributes so that they can be stored in shared memory mapped at different
addresses in each backend. This won't work for TupleDescs with contraints
and defaults, since those point to other objects, but for many purposes
only attributes are needed.

Commit 3eb9a5e7c unintentionally introduced an ordering dependency
into restore_toc_entries_prefork(). The existing coding of
reduce_dependencies() contains a check to skip moving a TOC entry
to the ready_list if it wasn't initially in the pending_list.
This used to suffice to prevent reduce_dependencies() from trying to
move anything into the ready_list during restore_toc_entries_prefork(),
because the pending_list stayed empty throughout that phase; but it no
longer does. The problem doesn't manifest unless the TOC has been
reordered by SortTocFromFile, which is how I missed it in testing.
To fix, just add a test for ready_list == NULL, converting the call
with NULL from a poor man's sanity check into an explicit command
not to touch TOC items' list membership. Clarify some of the comments
around this; in particular, note the primary purpose of the check for
pending_list membership, which is to ensure that we can't try to restore
the same item twice, in case a TOC list forces it to be restored before
its dependency count goes to zero.

previous commit.

It now emerges that we can only rely on Perl to tell us we must use
-D_USE_32BIT_TIME_T if it's Perl 5.13.4 or later. For older versions,
revert to our previous practice of assuming we need that symbol in
all 32-bit Windows builds. This is not ideal, but inquiring into
which compiler version Perl was built with seems far too fragile.
In any case, we had not previously had complaints about these old
Perl versions, so let's assume this is Good Enough. (It's still
better than the situation ante commit 5a5c2feca, in that at least
the effects are confined to PL/Perl rather than the whole PG build.)
Back-patch to all supported versions, like 5a5c2feca and predecessors.
