Thanks to Bruce for spotting it and Tom Lane for diagnosing it.
Since horology test output is changing anyway, add some date/time input
tests to horology.sql. Some of these should move to the tests for the
individual data types, and we perhaps should add an entire new test
for "timezone" to allow manipulating the current time zone without
risking damage to the results of other tests.

pg_regress doesn't see it and you don't get any port-specific
comparisons.

remove brain-dead rule that double quotes are needed if and only if the
datatype is pass-by-reference; neither direction of the implication holds
water. Instead, examine the actual data string to see if it contains
any characters that force us to quote it.
Add some documentation about quoting of array values, which was previously
explained nowhere AFAICT.

The default diff switches prevented regression tests from complaining,
but that doesn't make it correct.

recreated since the start of our transaction, our first reference to it
errored out because we'd try to reuse our old relcache entry for it.
Do this by accepting SI inval messages just before relcache search in
heap_openr, so that dead relcache entries will be flushed before we
search. Also, break heap_open/openr into two pairs of routines,
relation_open(r) and heap_open(r). The relation_open routines make
no tests on relkind and so can be used to open anything that has a
pg_class entry. The heap_open routines are wrappers that add a relkind
test to preserve their established behavior. Use the relation_open
routines in several places that had various kluge solutions for opening
rels that might be either heap or index rels.
Also, remove the old 'heap stats' code that's been superseded by Jan's
stats collector, and clean up some inconsistencies in error reporting
between the different types of ALTER TABLE.

Mask both typmod subfields for INTERVAL to avoid setting the high bit,
per dire warning from Tom Lane.
Clear tmask for DTK_ISO_TIME case to avoid time zone troubles.
Symptom reported by Tom Lane.
Clean up checking for valid time zone info in output routine.
This should now work for both SQL99 and Unix-style time zones.
Put in explicit check for INTERVAL() typmod rounding to avoid accumulating
cruft in the lower bits. Not sure that this helps, but we'll need to do
something. The symptom is visible with a query like
select interval(2) '10000 days 01:02:03.040506';
Regression tests are patched to repair the Tom Lane symptom, and all pass.

Modified the parser and the SET handlers to use full Node structures
rather than simply a character string argument.
Implement INTERVAL() YEAR TO MONTH (etc) syntax per SQL99.
Does not yet accept the goofy string format that goes along with, but
this should be fairly straight forward to fix now as a bug or later
as a feature.
Implement precision for the INTERVAL() type.
Use the typmod mechanism for both of INTERVAL features.
Fix the INTERVAL syntax in the parser:
opt_interval was in the wrong place.
INTERVAL is now a reserved word, otherwise we get reduce/reduce errors.
Implement an explicit date_part() function for TIMETZ.
Should fix coersion problem with INTERVAL reported by Peter E.
Fix up some error messages for date/time types.
Use all caps for type names within message.
Fix recently introduced side-effect bug disabling 'epoch' as a recognized
field for date_part() etc. Reported by Peter E. (??)
Bump catalog version number.
Rename "microseconds" current transaction time field
from ...Msec to ...Usec. Duh!
date/time regression tests updated for reference platform, but a few
changes will be necessary for others.

Also, update mb/expected/unicode.out. This is necessary since the
patches affetc the result of queries using UTF-8.
---------------------------------------------------------------
Hi,
I should have sent the patch earlier, but got delayed by other stuff.
Anyway, here is the patch:
- most of the functionality is only activated when MULTIBYTE is
defined,
- check valid UTF-8 characters, client-side only yet, and only on
output, you still can send invalid UTF-8 to the server (so, it's
only partly compliant to Unicode 3.1, but that's better than
nothing).
- formats with the correct number of columns (that's why I made it in
the first place after all), but only for UNICODE. However, the code
allows to plug-in routines for other encodings, as Tatsuo did for
the other multibyte functions.
- corrects a bit the UTF-8 code from Tatsuo to allow Unicode 3.1
characters (characters with values >= 0x10000, which are encoded on
four bytes).
- doesn't depend on the locale capabilities of the glibc (useful for
remote telnet).
I would like somebody to check it closely, as it is my first patch to
pgsql. Also, I created dummy .orig files, so that the two files I
created are included, I hope that's the right way.
Now, a lot of functionality is NOT included here, but I will keep that
for 7.3 :) That includes all string checking on the server side (which
will have to be a bit more optimised ;) ), and the input checking on
the client side for UTF-8, though that should not be difficult. It's
just to send the strings through mbvalidate() before sending them to
the server. Strong checking on UTF-8 strings is mandatory to be
compliant with Unicode 3.1+ .
Do I have time to look for a patch to include iso-8859-15 for 7.2 ?
The euro is coming 1. january 2002 (before 7.3 !) and over 280
millions people in Europe will need the euro sign and only iso-8859-15
and iso-8859-16 have it (and unfortunately, I don't think all Unices
will switch to Unicode in the meantime)....
err... yes, I know that this is not every single person in Europe that
uses PostgreSql, so it's not exactly 280m, but it's just a matter of
time ! ;)
I'll come back (on pgsql-hackers) later to ask a few questions
regarding the full unicode support (normalisation, collation,
regexes,...) on the server side :)
Here is the patch !
Patrice.

transformAlterStmt() use these routines, instead of having lots of
duplicate (not to mention should-have-been-duplicate) code.
Adding a column with a CHECK constraint actually works now,
and the tests to reject unsupported DEFAULT and NOT NULL clauses
actually fire now. ALTER TABLE ADD PRIMARY KEY works, modulo
having to have created the column(s) NOT NULL already.

'aggname (aggtype)'. The old syntax 'aggname aggtype' is still accepted
for backwards compatibility. Fix pg_dump, which was actually broken for
most cases of user-defined aggregates. Clean up error messages associated
with these commands.

time zones.
SQL99 spec requires a default of zero (round to seconds) which is set
in gram.y as typmod is set in the parse tree. We *could* change to a
default of either 6 (for internal compatibility with previous versions)
or 2 (for external compatibility with previous versions).
Evaluate entries in pg_proc wrt the iscachable attribute for timestamp and
other date/time types. Try to recognize cases where side effects like the
current time zone setting may have an effect on results to decide whether
something is cachable or not.

Modify the timestamp test to reflect the "no time zone" behavior of this
new code; timestamptz resembles the old timestamp code.

Frank Miles 7-Sep-01. This is really just sticking a finger in the dike.
Frank's case works now, but we still couldn't support a recursive function
returning a set. Really need to restructure querytrees and execution
state so that the querytree is *read only*. We've run into this over and
over and over again ... it has to happen sometime soon.
