doesn't take into account how far the WAL senders are. This way a hung
WAL sender doesn't prevent old WAL segments from being recycled/removed
in the primary, ultimately causing the disk to fill up. Instead add
standby_keep_segments setting to control how many old WAL segments are
kept in the primary. This also makes it more reliable to use streaming
replication without WAL archiving, assuming that you set
standby_keep_segments high enough.
At present, killing the startup process does not release any locks it holds,
so we must wait to stop the startup and walreceiver processes until all
read-only backends have exited. Without this patch, the startup and
walreceiver processes never exit, so the server gets permanently stuck in
a half-shutdown state.

isn't currently correct in backends during recovery, so the filename
returned was wrong.
is changed to match the hard-wired default. This avoids accumulating useless
catalog entries, and also provides a path for dropping the owning role without
using DROP OWNED BY. Per yesterday's complaint from Jaime Casanova, the
need to use DROP OWNED BY for that is less than obvious, so providing this
alternative method might save some user frustration.
The endterm attribute is mainly useful when the toolchain does not support
automatic link target text generation for a particular situation. In the
past, this was required by the man page tools for all reference page links,
but that is no longer the case, and it now actually gets in the way of
proper automatic link text generation. The only remaining use cases are
currently xrefs to refsects.
loop in standby mode, trying to restore from archive, pg_xlog and
streaming.
Move sections around to make the high availability chapter more
coherent: the most prominent part is now a "Log-Shipping Standby Servers"
section that describes what a standby server is (like the old
"Warm Standby Servers for High Availability" section), and how to
set up a warm standby server, including streaming replication, using the
built-in standby mode. The pg_standby method is desribed in another
section called "Alternative method for log shipping", with the added
caveat that it doesn't work with streaming replication.
It is no longer installed by default, but included in "make world"/"make
install-world". Documentation updated accordingly.
Also, fix vpathsearch function to work when calling make install-docs
without previous make docs.

setting.
Apply the same treatment to ALTER DATABASE d RESET ALL when run by a database
owner that's not superuser.
writes. The first worker still uses "pgbench_log.<pid>" for the name, but
additional workers use "pgbench_log.<pid>.<serial-number>" instead.

Docs were unclear on whether or not database=replication was required,
nor did they mention the FATAL error this causes if database parameter is
mentioned explicitly, whatever its value.
in recovery_end_command, it always came out as 0 because InRedo was
cleared before recovery_end_command was executed. Also, always take
ControlFileLock when reading checkpoint location for %r.
The recovery_end_command bug and the missing locking was present in 8.4
as well, that part of this patch will be backported separately.
