- Fix wrong index results on text, char, varchar for multibyte strings

- Add support for infinite timestamps
- Because of locale settings, btree_gist can not be a prefix index anymore (for text).
  Each node holds now just the lower and upper boundary.

pgtypeslib: (1) we need to check the return value of sub_abs() (2) we
need to check the return value of 4 calls to digitbuf_alloc().

non-NULL in this function, so there is no need to check for it (2) we
should check the return value of pgtypes_strdup(). Patch from Eric
Astor at EnterpriseDB, with slight cleanup by myself, per a report
from the Coverity tool.

- add forgotten check of lsn for insert completion
- remove level of pages: hard to check in recovery
- some cleanups

or zero-filled; therefore zero-filling it via memset() is pointless.
(I think setting `errno' is probably a waste of cycles as well, but I
haven't changed that.)

remove old-style function declarations, and mark a function "static".
There are some remaining warnings, but this fixes most of them, anyway.

include.

malloc() succeeded but the second failed, the buffer allocated by the
first malloc() would be leaked. Fix this by allocating both buffers
via a single malloc(), as suggested by Tom.

the difference between checkpoints forced due to WAL segment consumption
and checkpoints forced for other reasons (such as CREATE DATABASE).  Avoid
generating 'checkpoints are occurring too frequently' messages when the
checkpoint wasn't caused by WAL segment consumption.  Per gripe from
Chris K-L.

current time: provide a GetCurrentTimestamp() function that returns
current time in the form of a TimestampTz, instead of separate time_t
and microseconds fields.  This is what all the callers really want
anyway, and it eliminates low-level dependencies on AbsoluteTime,
which is a deprecated datatype that will have to disappear eventually.

role memberships; make superuser/createrole distinction do something
useful; fix some locking and CommandCounterIncrement issues; prevent
creation of loops in the membership graph.

In particular, make hba.c cope with zero-length tokens, which it
never did properly before.  Also, enforce rolcanlogin.

syntactic conflicts, both privilege and role GRANT/REVOKE commands have
to use the same production for scanning the list of tokens that might
eventually turn out to be privileges or role names.  So, change the
existing GRANT/REVOKE code to expect a list of strings not pre-reduced
AclMode values.  Fix a couple other minor issues while at it, such as
InitializeAcl function name conflicting with a Windows system function.

and pg_auth_members.  There are still many loose ends to finish in this
patch (no documentation, no regression tests, no pg_dump support for
instance).  But I'm going to commit it now anyway so that Alvaro can
make some progress on shared dependencies.  The catalog changes should
be pretty much done.

> * -Add concurrency to GIST

- full concurrency for insert/update/select/vacuum:
        - select and vacuum never locks more than one page simultaneously
        - select (gettuple) hasn't any lock across it's calls
        - insert never locks more than two page simultaneously:
                - during search of leaf to insert it locks only one page
                  simultaneously
                - while walk upward to the root it locked only parent (may be
                  non-direct parent) and child. One of them X-lock, another may
                  be S- or X-lock
- 'vacuum full' locks index
- improve gistgetmulti
- simplify XLOG records

Fix bug in index_beginscan_internal: LockRelation may clean
  rd_aminfo structure, so move GET_REL_PROCEDURE after LockRelation

name matches the name of any parent-table constraint, without looking
at the constraint text.  This is a not-very-bulletproof workaround for
the problem exhibited by Berend Tober last month.  We really ought to
record constraint inheritance status in pg_constraint, but it's looking
like that may not get done for 8.1 --- and even if it does, we will
need this kluge for dumping from older servers.

> * -Remove kerberos4 from source tree

some security issues, and upstream has declared it "dead". Patch from
Magnus Hagander, minor editorialization from Neil Conway.

wrong, but nobody noticed because they were also useless.

works properly for 1-D comparisons.  Fix some other errors such as
bogus commutator specifications.

with a table that has a small predicted size.  Avoids wasting several
hundred K on the timezone hash table, which is likely to have only one
or a few entries, but the entries use up 10Kb apiece ...

with main, avoid using a SQL-defined SQLSTATE for what is most definitely
not a SQL-compatible error condition, fix documentation omissions,
adhere to message style guidelines, don't use two GUC_REPORT variables
when one is sufficient.  Nothing done about pg_dump issues.
