Attached is a doc patch that does this. The way I've worded it may not
be the best, though.

I suggest adding LOCALTIMESTAMP and LOCALTIME to the first paragraph.
Maybe it should be phrased as:
The following SQL-compatible functions can be used to obtain
current datetime-related values: CURRENT_DATE, CURRENT_TIME,
CURRENT_TIMESTAMP, LOCALTIME and LOCALTIMESTAMP.

before it is de-backslashed, not after. This allows the null string \N
to be reliably distinguished from the data value \N (which must be
represented as \\N). Per bug report from Manfred Koizar ... but it's
amazing this hasn't been reported before ...
Also, be consistent about encoding conversion for null string: the form
specified in the command is in the server encoding, but what is sent
to/from client must be in client encoding. This never worked quite
right before either.

upgrade the routine's handling of double quotes to match the backend,
in particular support doubled double quotes within quoted identifiers.

need to adjust pg_dump to make use of it.
invalid (has the wrong magic number) until the build is entirely
complete. This turns out to cost no additional writes in the normal
case, since we were rewriting the metapage at the end of the process
anyway. In normal scenarios there's no real gain in security, because
a failed index build would roll back the transaction leaving an unused
index file, but for rebuilding shared system indexes this seems to add
some useful protection.

Attached are two patches:
- installdoc.patch contains an additional paragraph on the win32 console
codepage for the chapter "Installation on Windows"
Due to a lack of SGML-tools, I have only edited the text and not tested
the SGML code - please check it before merging into the CVS branch.
- psqlcodepage.patch adds the warning about a problematic codepage to psql.

now able to cope with assigning new relfilenode values to nailed-in-cache
indexes, so they can be reindexed using the fully crash-safe method. This
leaves only shared system indexes as special cases. Remove the 'index
deactivation' code, since it provides no useful protection in the shared-
index case. Require reindexing of shared indexes to be done in standalone
mode, but remove other restrictions on REINDEX. -P (IgnoreSystemIndexes)
now prevents using indexes for lookups, but does not disable index updates.
It is therefore safe to allow from PGOPTIONS. Upshot: reindexing system catalogs
can be done without a standalone backend for all cases except
shared catalogs.
to control object ownership. The use-set-session-authorization and
no-reconnect switches are obsolete (still accepted on the command line,
but they don't do anything). This is a precursor to fixing handling
of CREATE SCHEMA, which will be a separate commit.
