s/XIDs XIDs/XIDs/ in one place in maintenance.sgml.

- Capitalize titles consistently.
- Fix some grammar.
- Group "Obtaining Information About an Error" under "Trapping Errors",
but make "Obtaining the Call Stack Context Information" its own
section, since it's not about errors.

Previously the duplicated paragraphs were used next to each other
in the document to demonstrate that the changes in the stream
were not consumed by pg_logical_slot_peek_changes function.
But some users misunderstood that the duplication of the same
paragraph was just typo. So this commit rewords the sentence in
the latter paragraph for less confusing.

The documentation of ALTER TABLESPACE ... MOVE was added without any
markup, not even paragraph breaks. Fix that, and clarify the text in a
few places.

Break the list of available options into an <itemizedlist> instead of
inline sentences. This is mostly motivated by wanting to ensure that the
cross-references to the FSM and VM docs don't cross page boundaries in PDF
format; but it seems to me to read more easily this way anyway. I took the
liberty of editorializing a bit further while at it.
Per complaint from Magnus about 9.0.18 docs not building in A4 format.
Patch all active branches so we don't get blind-sided by this particular
issue again in future.

Rather remarkable that this has been wrong since 9.1 and nobody noticed.

~/.pgpass is a sound choice everywhere, and "peer" authentication is
safe on every platform it supports. Cease to recommend "trust"
authentication, the safety of which is deeply configuration-specific.
Back-patch to 9.0, where pg_upgrade was introduced.

The old name wasn't very descriptive as of actual contents of the
directory, which are historical snapshots in the snapshots/
subdirectory and mappingdata for rewritten tuples in
mappings/. There's been a fair amount of discussion what would be a
good name. I'm settling for pg_logical because it's likely that
further data around logical decoding and replication will need saving
in the future.
Also add the missing entry for the directory into storage.sgml's list
of PGDATA contents.
Bumps catversion as the data directories won't be compatible.
Backpatch to 9.4, which I missed to do as Michael Paquier luckily
noticed. As there already has been a catversion bump after 9.4beta1,
there's no reasons for having 9.4 diverge from master.

The "false" case was really quite useless since all it did was to throw
an error; a definition not helped in the least by making it the default.
Instead let's just have the "true" case, which emits nested objects and
arrays in JSON syntax. We might later want to provide the ability to
emit sub-objects in Postgres record or array syntax, but we'd be best off
to drive that off a check of the target field datatype, not a separate
argument.
For the functions newly added in 9.4, we can just remove the flag arguments
outright. We can't do that for json_populate_record[set], which already
existed in 9.3, but we can ignore the argument and always behave as if it
were "true". It helps that the flag arguments were optional and not
documented in any useful fashion anyway.

These should not have existed to begin with, but there was apparently some
misunderstanding of the purpose of the opr_sanity regression test item
that checks for operator implementation functions with their own comments.
The idea there is to check for unintentional violations of the rule that
operator implementation functions shouldn't be documented separately
.... but for these functions, that is in fact what we want, since the
variadic option is useful and not accessible via the operator syntax.
Get rid of the extra pg_proc entries and fix the regression test and
documentation to be explicit about what we're doing here.

7380b63 changed log_filename so that epoch was not appended to it
when no format specifier is given. But the example of CSV log file name
with epoch still left in log_filename document. This commit removes
such obsolete example.
This commit also documents the defaults of log_directory and
log_filename.
Backpatch to all supported versions.

By using curly braces, the template had specified that one of
"NOT DEFERRABLE", "INITIALLY IMMEDIATE", or "INITIALLY DEFERRED"
was required on any CREATE TRIGGER statement, which is not
accurate. Change to square brackets makes that optional.
Backpatch to 9.1, where the error was introduced.

data_directory could be set both in postgresql.conf and postgresql.auto.conf so far.
This could cause some problematic situations like circular definition. To avoid such
situations, this commit forbids a user to set data_directory in postgresql.auto.conf.
Backpatch this to 9.4 where ALTER SYSTEM command was introduced.

Report by Peter Geoghegan

|
Any OS user able to access the socket can connect as the bootstrap
superuser and proceed to execute arbitrary code as the OS user running
the test. Protect against that by placing the socket in a temporary,
mode-0700 subdirectory of /tmp. The pg_regress-based test suites and
the pg_upgrade test suite were vulnerable; the $(prove_check)-based test
suites were already secure. Back-patch to 8.4 (all supported versions).
The hazard remains wherever the temporary cluster accepts TCP
connections, notably on Windows.
As a convenient side effect, this lets testing proceed smoothly in
builds that override DEFAULT_PGSOCKET_DIR. Popular non-default values
like /var/run/postgresql are often unwritable to the build user.

Back-patch to 9.4.

The previous naming broke the query that libpq's lo_initialize() uses
to collect the OIDs of the server-side functions it requires, because
that query effectively assumes that there is only one function named
lo_create in the pg_catalog schema (and likewise only one lo_open, etc).
While we should certainly make libpq more robust about this, the naive
query will remain in use in the field for the foreseeable future, so it
seems the only workable choice is to use a different name for the new
function. lo_from_bytea() won a small straw poll.
Back-patch into 9.4 where the new function was introduced.

Previously there's been a mix between 'slotname' and 'slot_name'. It's
not nice to be unneccessarily inconsistent in a new feature. As a post
beta1 initdb now is required in the wake of eeca4cd35e, fix the
inconsistencies.
Most the changes won't affect usage of replication slots because the
majority of changes is around function parameter names. The prominent
exception to that is that the recovery.conf parameter
'primary_slotname' is now named 'primary_slot_name'.

Back-patch to 9.3 where pg_stat directory was introduced.

Previously, any backslash in text being escaped for JSON was doubled so
that the result was still valid JSON. However, this led to some perverse
results in the case of Unicode sequences, These are now detected and the
initial backslash is no longer escaped. All other backslashes are
still escaped. No validity check is performed, all that is looked for is
\uXXXX where X is a hexidecimal digit.
This is a change from the 9.2 and 9.3 behaviour as noted in the Release
notes.
Per complaint from Teodor Sigaev.

Many JSON processors require timestamp strings in ISO 8601 format in
order to convert the strings. When converting a timestamp, with or
without timezone, to a JSON datum we therefore now use such a format
rather than the type's default text output, in functions such as
to_json().
This is a change in behaviour from 9.2 and 9.3, as noted in the release
notes.

Document the CREATE_REPLICATION_SLOT's output_plugin parameter; that
START_REPLICATION ... LOGICAL takes parameters; that START_REPLICATION
... LOGICAL uses the same messages as ... PHYSICAL; and be more
consistent with the usage of <literal/>.

Allow the contrib/uuid-ossp extension to be built atop any one of these
three popular UUID libraries. (The extension's name is now arguably a
misnomer, but we'll keep it the same so as not to cause unnecessary
compatibility issues for users.)
We would not normally consider a change like this post-beta1, but the issue
has been forced by our upgrade to autoconf 2.69, whose more rigorous header
checks are causing OSSP's header files to be rejected on some platforms.
It's been foreseen for some time that we'd have to move away from depending
on OSSP UUID due to lack of upstream maintenance, so this is a down payment
on that problem.
While at it, add some simple regression tests, in hopes of catching any
major incompatibilities between the three implementations.
Matteo Beccati, with some further hacking by me
