Add a random number generator and seed setter (random(), SET SEED)
Fix up the interval*float8 math to carry partial months
into the time field.
Add float8*interval so we have symmetry in the available math.
Fix the parser and define.c to accept SQL92 types as field arguments.
Fix the parser to accept SQL92 types for CREATE TYPE, etc. This is
necessary to allow...
Bit/varbit support in contrib/bit cleaned up to compile and load
cleanly. Still needs some work before final release.
Implement the "SOME" keyword as a synonym for "ANY" per SQL92.
Implement ascii(text), ichar(int4), repeat(text,int4) to help
support the ODBC driver.
Enable the TRUNCATE() function mapping in the ODBC driver.

input, not throw a gratuitous elog().

Implement TIME WITH TIME ZONE type (timetz internal type).
Remap length() for character strings to CHAR_LENGTH() for SQL92
and to remove the ambiguity with geometric length() functions.
Keep length() for character strings for backward compatibility.
Shrink stored views by removing internal column name list from visible rte.
Implement min(), max() for time and timetz data types.
Implement conversion of TIME to INTERVAL.
Implement abs(), mod(), fac() for the int8 data type.
Rename some math functions to generic names:
round(), sqrt(), cbrt(), pow(), etc.
Rename NUMERIC power() function to pow().
Fix int2 factorial to calculate result in int4.
Enhance the Oracle compatibility function translate() to work with string
arguments (from Edwin Ramirez).
Modify pg_proc system table to remove OID holes.

rather than returning a NaN for bogus input to pow(). Namely, HPUX 10.20.
I think this is sufficient evidence for what I thought all along, which
is that the float.c code *must* look at errno whether finite() exists or
not.

works if finite() is a function. Patch from Christof Petig.

with no input rows, per pghackers discussions around 7/22/99. Clean up
a bunch of ugly coding while at it; remove redundant re-lookup of
aggregate info at start of each new GROUP. Arrange to pfree intermediate
values when they are pass-by-ref types, so that aggregates on pass-by-ref
types no longer eat memory. This takes care of a couple of TODO items...

and related files. Also remove float.c's gratuitous redeclaration of
isinf() ... looks like there are more decls in there that ought to be
in config.h, but I'll leave well enough alone for now ...

was causing it not to detect out-of-range float values, as evidenced by
failure of float8 regression test. I corrected that logic and also
modified expected float8 results to account for new error message
generated for out-of-range inputs.

I think NAN is already guaranteed to be there from Jan's work on NUMERIC,
but perhaps HUGE_VAL needs some #ifndef's in the same place.
Should also include "-Infinity" as -HUGE_VAL sometime; not there yet.

than silently returning zero on some machines. Correct float8 regress test
to agree. Also fix pow() overflow/underflow check to work correctly on
HPUX.

This will fix the problem reported by Jose' Soares
when trying to cast a float to text.

Ok, I have finally gotten all of the defines for Dec/Alpha and
Linux/Alpha sorted out as Marc asked. There is no longer any need for
'-Dalpha' or '-Dlinuxalpha' in either the Dec/Alpha or the Linux/Alpha
template files (./src/template/{alpha,linuxalpha}). I have replaced every
instance of 'alpha' or '__alpha__' with '__alpha', as that appears to be
the common symbol between C compilers on both operating systems (RH4.2 &
DecUnix 4.0b) for alpha.

Add type conversion functions for floating point numbers.
Check for zero in unary minus floating point code (IEEE allows an
explicit negative zero which looks ugly in a query result!).
Ensure circle type has non-negative radius.

Subject: [HACKERS] linux/alpha patches
These patches lay the groundwork for a Linux/Alpha port. The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start. It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.
