and history files as per recent discussion.  While at it, remove
pg_terminate_backend, since we have decided we do not have time during
this release cycle to address the reliability concerns it creates.
Split the 'Miscellaneous Functions' documentation section into
'System Information Functions' and 'System Administration Functions',
which hopefully will draw the eyes of those looking for such things.

better SQL compliance in this area, per recent discussion.  Mark related
operators as commutators where possible.  (The system doesn't actually care
about commutator marking for operators not returning boolean, at the moment,
but this seems forward-thinking and besides it made it easier to verify
that we hadn't missed any.)
Also, remove interval-minus-time and interval-minus-timetz operators.
I'm not sure how these got in, but they are nonstandard and had very
obviously broken behavior.  (minus is not commutative in anyone's book.)
I doubt anyone had ever used 'em, because we'd surely have gotten a bug
report about it if so.

 From an idea of Bruce, the attached patch implements the function
 pg_tablespace_databases(oid) RETURNS SETOF oid
 which delivers as set of database oids having objects in the selected
 tablespace, enabling an admin to examine only the databases affecting
 the tablespace for objects instead of scanning all of them.

initdb forced

This eliminates the assumption that a serial column's sequence will
have the same name on reload that it was given in the original database.

eliminating the former hard-wired convention about their names.  Allow
pg_cast entries to represent both type coercion and length coercion in
a single step --- this is represented by a function that takes an
extra typmod argument, just like a length coercion function.  This
nicely merges the type and length coercion mechanisms into something
at least a little cleaner than we had before.  Make use of the single-
coercion-step behavior to fix integer-to-bit coercion so that coercing
to bit(n) yields the rightmost n bits of the integer instead of the
leftmost n bits.  This should fix recurrent complaints about the odd
behavior of this coercion.  Clean up the documentation of the bit string
functions, and try to put it where people might actually find it.
Also, get rid of the unreliable heuristics in ruleutils.c about whether
to display nested coercion steps; instead require parse_coerce.c to
label them properly in the first place.

log_hostname is enabled, clean up documentation.

Specifically, point out that intersecting points in a path will yield
(most likely), unexpected results.  Visually these are identical paths,
but mathematically they're not the same.  Ex:

  area |                                           plan
------
+-----------------------------------------------------------------------
-------------------
    -0 | ((0,0),(0,1),(2,1),(2,2),(1,2),(1,0),(0,0))
     2 | ((0,0),(0,1),(1,1),(1,2),(2,2),(2,1),(1,1),(1,0),(0,0))

The current algorithm for area(PATH) is very quick, but only handles
non-intersecting paths.  I'm going to work on two other functions for
the PATH data type that determines if a PATH is intersecting or not,
and a function that returns the area() for an intersecting PATH.  The
intersecting area() function will be considerably slower (I think it's
going to be O(n!) or worse instead of the current O(n), but that comes
with the territory).

patch-tmp-schema.txt contains the following bits:

*) Changes pg_namespace_aclmask() so that the superuser is always able
to create objects in the temp namespace.
*) Changes pg_namespace_aclmask() so that if this is a temp namespace,
objects are only allowed to be created in the temp namespace if the
user has TEMP privs on the database.  This encompasses all object
creation, not just TEMP tables.
*) InitTempTableNamespace() checks to see if the current user, not the
session user, has access to create a temp namespace.

The first two changes are necessary to support the third change.  Now
it's possible to revoke all temp table privs from non-super users and
limiting all creation of temp tables/schemas via a function that's
executed with elevated privs (security definer).  Before this change,
it was not possible to have a setuid function to create a temp
table/schema if the session user had no TEMP privs.

patch-area-path.txt contains:

*) Can now determine the area of a closed path.


patch-dfmgr.txt contains:

*) Small tweak to add the library path that's being expanded.

I was using $lib/foo.so and couldn't easily figure out what the error
message, "invalid macro name in dynamic library path" meant without
looking through the source code.  With the path in there, at least I
know where to start looking in my config file.
