and rules alphabetically in the output. This makes it the same as
for indexes and stops the irritating random or reverse ordering it
currently has.

clause implicitly whenever one is not given explicitly. Remove concept
of a schema having an associated tablespace, and simplify the rules for
selecting a default tablespace for a table or index. It's now just
(a) explicit TABLESPACE clause; (b) default_tablespace if that's not an
empty string; (c) database's default. This will allow pg_dump to use
SET commands instead of tablespace clauses to determine object locations
(but I didn't actually make it do so). All per recent discussions.
There are various things left to do: contrib dbsize and oid2name modules
need work, and so does the documentation. Also someone should think about
COMMENT ON TABLESPACE and maybe RENAME TABLESPACE. Also initlocation is
dead, it just doesn't know it yet.

conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.
little more sane. Some parts of the code was using a static function
xmalloc() that did safe memory allocation (where "safe" means "bail
out on OOM"), but most of it was just invoking calloc() or malloc()
directly. Now almost everything invokes xmalloc() or xcalloc().
definitions use pretty printing.
It does:
* Pretty index predicates
* Pretty rule definitions
* Uppercases PRIMARY KEY and UNIQUE to be consistent with CHECK and
FOREIGN KEY
* View rules are improved to match table rules:

o allow configure to see include/port/win32 include files
o add matching Win32 accept() prototype
o allow pg_id to compile with native Win32 API
o fix invalide mbvalidate() function calls (existing bug)
o allow /scripts to compile with native Win32 API
o add win32.c to Win32 compiles (already in *.mak files)
psql4win32.patch - changes in the psql source code
psql-ref.patch - changes in the documentation psql-ref.sgml
(for new builtin variable WIN32_CONSOLE)
To apply them use "patch -p 1" in the root directory of the
postgres source directory.
These patches fix the following problems of psql on Win32
(all changes only have effect #ifdef WIN32):
a) Problem: Static library libpq.a did not work
Solution: Added WSAStartup() in fe-connect.c
b) Problem: Secret Password was echoed by psql
Solution: Password echoing disabled in sprompt.c
c) Problem: 8bit characters were displayed/interpreted wrong in psql
This is due to the fact that the Win32 "console" uses a
different encoding than the rest of the Windows system
Solution: Introduced a new psql variable WIN32_CONSOLE
When set with "\set WIN32_console", the function OemToChar()
is applied after reading input and CharToOem() before
displaying Output

of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects). This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up. Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.
Example:
test=# \d test
Table "public.test"
Column | Type | Modifiers
--------+---------+-----------
a | integer | not null
Indexes:
"test_pkey" PRIMARY KEY btree (a)
Check Constraints:
"$2" CHECK (a > 1)
Foreign Key Constraints:
"$1" FOREIGN KEY (a) REFERENCES parent(b)
Rules:
myrule AS ON INSERT TO test DO INSTEAD NOTHING
Triggers:
"asdf asdf" AFTER INSERT OR DELETE ON test FOR EACH STATEMENT EXECUTE
PROCEDURE update_pg_pwd_and_pg_group(),
mytrigger AFTER INSERT OR DELETE ON test FOR EACH ROW EXECUTE PROCEDURE
update_pg_pwd_and_pg_group()
I have minimised the double quoting of identifiers as much as I could
easily, and I will submit another patch when I have time to work on it that
will use a 'fmtId' function to determine it exactly.
I think it's a significant improvement in legibility...
Obviously the table example above is slightly degenerate in that not many
tables in production have heaps of (non-constraint) triggers and rules.

* Add schema, cast, and conversion backslash commands to psql
I had to create a new publically available function,
pg_conversion_is_visible, as it seemed to be missing from the catalogs.
This required me to do no small amount of hacking around in namespace.c
I have updated the \? help and sgml docs.
\dc - list conversions [PATTERN]
\dC - list casts
\dn list schemas
I didn't support patterns with casts as there's nothing obvious to match
against.
Catalog version incremented --- initdb required.
