0163983330 When checking for thread safety with src/tools/thread/thread_test.c, the
mktemp function wants an argument that contains 6 X, while the current
version only supplies 5 X which will fail on my SuSE 8.1.

d707495452 Fix thinko in recent patch to change temp-table permissions behavior:
this is an aclmask function and does not have the same return convention
as aclcheck functions.  Also adjust the behavior so that users without
CREATE TEMP permission still have USAGE permission on their session's
temp schema.  This allows privileged code to create a temp table and
make it accessible to code that's not got the same privilege.  (Since
the default permissions on a table are no-access, an explicit grant on
the table will still be needed; but I see no reason that the temp schema
itself should prohibit such access.)

1a321f26d8 Code review for EXEC_BACKEND changes. Reduce the number of #ifdefs by
about a third, make it work on non-Windows platforms again.  (But perhaps
I broke the WIN32 code, since I have no way to test that.)  Fold all the
paths that fork postmaster child processes to go through the single
routine SubPostmasterMain, which takes care of resurrecting the state that
would normally be inherited from the postmaster (including GUC variables).
Clean up some places where there's no particularly good reason for the
EXEC and non-EXEC cases to work differently.  Take care of one or two
FIXMEs that remained in the code.

16974ee910 Get rid of the former rather baroque mechanism for propagating the values
of ThisStartUpID and RedoRecPtr into new backends.  It's a lot easier just
to make them all grab the values out of shared memory during startup.
This helps to decouple the postmaster from checkpoint execution, which I
need since I'm intending to let the bgwriter do it instead, and it also
fixes a bug in the Win32 port: ThisStartUpID wasn't getting propagated at
all AFAICS.  (Doesn't give me a lot of faith in the amount of testing that
port has gotten.)

4646a8f32f Reduce the minimum allocable chunk size to 8 bytes (from 16). Now that
ListCells are only 8 bytes instead of 12 (on 4-byte-pointer machines
anyway), it's worth maintaining a separate freelist for 8-byte objects.
Remembering that alloc chunks carry 8 bytes of overhead, this should
reduce the net storage requirement for a long List by about a third.

97d625dd1c *) inet_(client|server)_(addr|port)() and necessary documentation for
the four functions.


> Also, please justify the temp-related changes.  I was not aware that we
> had any breakage there.

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.

8096fe45ce The added aggregates are:
(1) boolean-and and boolean-or aggregates named bool_and and bool_or.
    they (SHOULD;-) correspond to standard sql every and some/any aggregates.
    they do not have the right name as there is a problem with
    the standard and the parser for some/any. Tom also think that
    the standard name is misleading because NULL are ignored.
    Also add 'every' aggregate.

(2) bitwise integer aggregates named bit_and and bit_or for
    int2, int4, int8 and bit types. They are not standard, but I find
    them useful. I needed them once.


The patches adds:

- 2 new very short strict functions for boolean aggregates in
  src/backed/utils/adt/bool.c,
  src/include/utils/builtins.h and src/include/catalog/pg_proc.h

- the new aggregates declared in src/include/catalog/pg_proc.h and
  src/include/catalog/pg_aggregate.h

- some documentation and validation about these new aggregates.

3dc37cd8d6 The patch adresses the TODO list item "Allow external interfaces to
extend the GUC variable set".

Plugin modules like the pl<lang> modules needs a way to declare
configuration parameters. The postmaster has no knowledge of such
modules when it reads the postgresql.conf file. Rather than allowing
totally unknown configuration parameters, the concept of a variable
"class" is introduced. Variables that belongs to a declared classes will
create a placeholder value of string type and will not generate an
error. When a module is loaded, it will declare variables for such a
class and make those variables "consume" any placeholders that has been
defined. Finally, the module will generate warnings for unrecognized
placeholders defined for its class.

More detail:
The design is outlined after the suggestions made by Tom Lane and Joe
Conway in this thread:

http://archives.postgresql.org/pgsql-hackers/2004-02/msg00229.php

A new string variable 'custom_variable_classes' is introduced. This
variable is a comma separated string of identifiers. Each identifier
denots a 'class' that will allow its members to be added without error.
This variable must be defined in postmaster.conf.

The lexer (guc_file.l) is changed so that it can accept a qualified name
in the form <ID>.<ID> as the name of a variable. I also changed so that
the 'custom_variable_classes', if found, is added first of all variables
in order to remove the order of declaration issue.

The guc_variables table is made more dynamic. It is originally created
with 20% slack and can grow dynamically. A capacity is introduced to
avoid resizing every time a new variable is added. guc_variables and
num_guc_variables becomes static (hidden).

The GucInfoMain now uses the new function get_guc_variables() and
GetNumConfigOptions  instead or using the guc_variables directly.

The find_option() function, when passed a missing name, will check if
the name is qualified. If the name is qualified and if the qualifier
denotes a class included in the 'custom_variable_classes', a placeholder
variable will be created. Such a placeholder will not participate in a
list operation but will otherwise function as a normal string variable.

Define<type>GucVariable() functions will be added, one for each variable
type. They are inteded to be used by add-on modules like the pl<lang>
mappings. Example:

extern void DefineCustomBoolVariable(
         const char* name,
         const char* short_desc,
         const char* long_desc,
         bool* valueAddr,
         GucContext context,
         GucBoolAssignHook assign_hook,
         GucShowHook show_hook);

(I created typedefs for the assign-hook and show-hook functions). A call
to these functions will define a new GUC-variable. If a placeholder
exists it will be replaced but it's value will be used in place of the
default value. The valueAddr is assumed ot point at a default value when
the define function is called. The only constraint that is imposed on a
Custom variable is that its name is qualified.

Finally, a function:

void EmittWarningsOnPlacholders(const char* className)

was added. This function should be called when a module has completed
its variable definitions. At that time, no placeholders should remain
for the class that the module uses. If they do, elog(INFO, ...) messages
will be issued to inform the user that unrecognized variables are
present.

cfbfdc557d This patch implement the TODO [ALTER DATABASE foo OWNER TO bar].
It was necessary to touch in grammar and create a new node to make home
to the new syntax. The command is also supported in E
CPG. Doc updates are attached too. Only superusers can change the owner
of the database. New owners don't need any aditional
privileges.

d0b4399d81 Reimplement the linked list data structure used throughout the backend.
In the past, we used a 'Lispy' linked list implementation: a "list" was
merely a pointer to the head node of the list. The problem with that
design is that it makes lappend() and length() linear time. This patch
fixes that problem (and others) by maintaining a count of the list
length and a pointer to the tail node along with each head node pointer.
A "list" is now a pointer to a structure containing some meta-data
about the list; the head and tail pointers in that structure refer
to ListCell structures that maintain the actual linked list of nodes.

The function names of the list API have also been changed to, I hope,
be more logically consistent. By default, the old function names are
still available; they will be disabled-by-default once the rest of
the tree has been updated to use the new API names.

76c50c080b Add code to identify_system_timezone() to try all zones in the zic

grim but it seems to take less than a second even on a relatively slow
machine, and since it only happens once during postmaster startup, that
seems acceptable.
