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.

The patch adds one more place to look for readline headers, and a test
for replace_history_entry. I've only included the patch for configure.in

a definition or not.

Per Tom Lane's suggestion the information whether a tuple has an oid

tdhasoid is of type char, not bool. There are predefined values for

This patch has been generated against a cvs snapshot from last week
and I don't expect it to apply cleanly to current sources. While I
post it here for public review, I'm working on a new version against a
current snapshot. (There's been heavy activity recently; hope to
catch up some day ...)
This is a long patch; if it is too hard to swallow, I can provide it
in smaller pieces:
Part 1: Accessor macros
Part 2: tdhasoid in TupDesc
Part 3: Regression test
Part 4: Parameter withoid to heap_addheader
Part 5: Eliminate t_oid from HeapTupleHeader
Part 2 is the most hairy part because of changes in the executor and
even in the parser; the other parts are straightforward.
Up to part 4 the patched postmaster stays binary compatible to
databases created with an unpatched version. Part 5 is small (100
lines) and finally breaks compatibility.

As proof of concept, provide an alternate implementation based on POSIX
semaphores. Also push the SysV shared-memory implementation into a
separate file so that it can be replaced conveniently.
Use "--enable-integer-datetimes" in configuration to use this rather
than the original float8 storage. I would recommend the integer-based
storage for any platform on which it is available. We perhaps should
make this the default for the production release.
Change timezone(timestamptz) results to return timestamp rather than
a character string. Formerly, we didn't have a way to represent
timestamps with an explicit time zone other than freezing the info into
a string. Now, we can reasonably omit the explicit time zone from the
result and return a timestamp with values appropriate for the specified
time zone. Much cleaner, and if you need the time zone in the result
you can put it into a character string pretty easily anyway.
Allow fractional seconds in date/time types even for dates prior to 1BC.
Limit timestamp data types to 6 decimal places of precision. Just right
for a micro-second storage of int8 date/time types, and reduces the
number of places ad-hoc rounding was occuring for the float8-based types.
Use lookup tables for precision/rounding calculations for timestamp and
interval types. Formerly used pow() to calculate the desired value but
with a more limited range there is no reason to not type in a lookup
table. Should be *much* better performance, though formerly there were
some optimizations to help minimize the number of times pow() was called.
Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option
"--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED.
Add explicit date/interval operators and functions for addition and
subtraction. Formerly relied on implicit type promotion from date to
timestamp with time zone.
Change timezone conversion functions for the timetz type from "timetz()"
to "timezone()". This is consistant with other time zone coersion
functions for other types.
Bump the catalog version to 200204201.
Fix up regression tests to reflect changes in fractional seconds
representation for date/times in BC eras.
All regression tests pass on my Linux box.
compile in client apps that use the standard installed header set.
To allow removing that include, move DLLIMPORT definitions out of c.h
and into the appropriate port-specific header files.
int8, int16, int32, int64 and separately uint8, uint16, uint32, uint64
The previous patch grouped:
int8, int16 and int32
uint8, uint16 and uint32
int64 and uint64 <-- this grouping is wrong on AIX 4.3.3 and below
If you prefer to make 4 groups out of this you could apply this patch.

Enabling this feature adds very light overhead of 1 select from pg_class on
first using of pl/tcl in backend if unknown suppport is really unused.
But pl/tcl with this support has very improved functionality.

You can now set MaxBackends as high as your kernel can stand without

See attached revised patch. (I'm sure the configure.in stuff can be done
right/better, I'm just not enough of a autoconf guru to know what to
change it to.)
