wrong schema search path, etc. This is just the backend patch, still
need to adjust pg_dump to make use of it.

discussion on pgsql-hackers: in READ COMMITTED mode we just have to force
a QuerySnapshot update in the trigger, but in SERIALIZABLE mode we have
to run the scan under a current snapshot and then complain if any rows
would be updated/deleted that are not visible in the transaction snapshot.
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.
Before patch:
test=# select pg_get_constraintdef(oid) from pg_constraint;
pg_get_constraintdef
-------------------------------------------------------------------------------------------------
CHECK (VALUE >= 0)
CHECK ((((a)::text = 'asdf'::text) OR ((a)::text = 'fdsa'::text)) OR
((a)::text = 'dfd'::text))
PRIMARY KEY (b)
FOREIGN KEY (a) REFERENCES test2(b)
UNIQUE (b)
(5 rows)
test=# select pg_get_constraintdef(oid, true) from pg_constraint;
pg_get_constraintdef
-----------------------------------------------------------------------------------
CHECK VALUE >= 0
CHECK a::text = 'asdf'::text OR a::text = 'fdsa'::text OR a::text =
'dfd'::text
PRIMARY KEY (b)
FOREIGN KEY (a) REFERENCES test2(b)
UNIQUE (b)
(5 rows)
After patch:
test=# select pg_get_constraintdef(oid) from pg_constraint;
pg_get_constraintdef
-------------------------------------------------------------------------------------------------
CHECK (VALUE >= 0)
CHECK ((((a)::text = 'asdf'::text) OR ((a)::text = 'fdsa'::text)) OR
((a)::text = 'dfd'::text))
PRIMARY KEY (b)
FOREIGN KEY (a) REFERENCES test2(b)
UNIQUE (b)
(5 rows)
test=# select pg_get_constraintdef(oid, true) from pg_constraint;
pg_get_constraintdef
-----------------------------------------------------------------------------------
CHECK (VALUE >= 0)
` CHECK (a::text = 'asdf'::text OR a::text = 'fdsa'::text OR a::text =
'dfd'::text)
PRIMARY KEY (b)
FOREIGN KEY (a) REFERENCES test2(b)
UNIQUE (b)
(5 rows)
It's important that those brackets are there to (a) match all other
constraints and (b) so that people can just copy and paste them and it
will work as SQL.

areas are for the lifetime of the backend and in the interests of not breaking
something that's not broken I left alone.
Note for anyone reading this and wanting it for tsearch-v2-stable (i.e. for 7.3
backend) this patch probably will not apply cleanly to that source. It should
be simple enough to see what's going on and apply the changes by hand if need
be.

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.
