b32cac8055 Fix Joubert's complaint that int8-sized numeric literals are mishandled
on Alpha (because parser mistakenly assumes that a nonoverflow result
from strtol means the value will fit into int4).  A scan for other uses
of strtol and strtoul found a couple other places with the same mistake;
fix them too.  The changes are all conditional on HAVE_LONG_INT_64 to
avoid complaints from compilers that think x != x is a silly test
(cf. pg_atoi).

be92ad49e0 Change case-folding of keywords to conform to SQL99 and fix misbehavior
in Turkish locale.  Keywords are now checked under pure ASCII case-folding
rules ('A'-'Z'->'a'-'z' and nothing else).  However, once a word is
determined not to be a keyword, it will be case-folded under the current
locale, same as before.  See pghackers discussion 20-Feb-01.

a27b691e29 Ensure that all uses of <ctype.h> functions are applied to unsigned-char
values, whether the local char type is signed or not.  This is necessary
for portability.  Per discussion on pghackers around 9/16/00.

6b19803e06 Make a pstrdup copy of the literalbuf when scanning a bit string. Other-
wise the next bit string in the same command clobbers the previous ones.

0babf31640 Change internal string representation of BitString node to include a
leading 'b', as it appears to be more convenient this way for the input
and node functions.

73874a06f0 Change the parser to convert SQL "position" and "substring" syntax to
position() and substring() functions, so that it works transparently for
bit types as well.  Alias the text functions appropriately.

Add position() for bit types.

Add new constant node T_BitString that represents literals of the form
B'1001 and pass those to zpbit type.

ed5003c584 First cut at full support for OUTER JOINs. There are still a few loose
ends to clean up (see my message of same date to pghackers), but mostly
it works.  INITDB REQUIRED!

take 'em out of pg_operator.  Also remove from scan.l's set of legal
operator characters.  Update documentation.

df40234639 Support SQL99 embedded double-quote syntax for quoted identifiers.
Allow this in the parser and in pg_dump, but it is probably not enough
 for a complete solution.
Better to have the feature started then never here.

be703cd9e8 Implement nested block comments in the backend and in psql.
Include updates for the comment.sql regression test.
Implement SET SESSION CHARACTERISTICS and SET DefaultXactIsoLevel.
Implement SET SESSION CHARACTERISTICS TRANSACTION COMMIT
 and SET AutoCommit in the parser only.
 Need to add code to actually do something.
Implement WITHOUT TIME ZONE type qualifier.
Define SCHEMA keyword, along with stubbed-out grammar.
Implement "[IN|INOUT|OUT] [varname] type" function arguments
 in parser only; INOUT and OUT throws an elog(ERROR).
Add PATH as a type-specific token, since PATH is in SQL99
 to support schema resource search and resolution.

44d1abebb4 Big warnings cleanup for Solaris/GCC. Down to about 40 now, but
we'll get there one day.

Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.

Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.

f945f46193 Modify lexing of multi-char operators per pghackers discussion around
16-Mar-00: trailing + or - is not part of the operator unless the operator
also contains characters not present in SQL92-defined operators.  This
solves the 'X=-Y' problem without unduly constraining users' choice of
operator names --- in particular, no existing Postgres operator names
become invalid.

Also, remove processing of // comments, as agreed in the same thread.

a84c95634e Performance improvement for lexing long strings: increase flex's
YY_READ_BUF_SIZE, which turns out to have nothing to do with buffer size.
It's just a totally arbitrary upper limit on how much data myinput() is
asked for at one time.

f3a9d75ebd Finish cleaning up backend's handling of /* ... */ and -- comments,
per pghackers discussion around 20-Feb.  Also add specific error messages
for unterminated comments and unterminated quoted strings.  These things
are nonissues for input coming from psql, but they do matter for input
coming from other front ends.

393f313227 Change parse-time representation of float literals (which include oversize
integers) to be strings instead of 'double'.  We convert from string form
to internal representation only after type resolution has determined the
correct type for the constant.  This eliminates loss-of-precision worries
and gets rid of the change in behavior seen at 17 digits with the
previous kluge.

3cfdd8fdf2 Clean up scan.l's handling of \r vs \n --- they are reliably treated as
equivalent now, which should make Windows and Mac clients happier.
Also fix failure to handle SQL comments between segments of a multiline
quoted literal.

8e35bbd133 Remove fixed-size literal buffer from scan.l, and repair
boundary-condition bug in myinput() which caused flex scanner to fail
on tokens larger than a bufferload.  Turns out flex doesn't want null-
terminated input ... and if it gives you a 1-character buffer, you'd
better supply a character, not a null, lest you be thought to be
reporting end of input.

Bruce Momjian
341e360d67 Sorry, guys. Here is the ultimate patch which keeps the entire
behavior as it was, apart from forbidding minus-terminated
operators. Seems that I have to break the habit of doing before
thinking properly :-/  The point is that my second patch breaks
constructs like a & b  or   a ! b. This patch is to be applied
instead of any of two other today's patches.

7d7fb02148 Following advice from Michael Ansley, I broke up the patch in
two: one fixes uminus and other literal length. They are to be
applied - uminus first, then possilbly literal on top of uminus.

Tom Lane
85712da90d Mike Ansley's fixes for long queries. This change just
corrects flex myinput() routine so that it doesn't assume there is only
one bufferload of data.  We still have the issue of getting rid of
YY_USES_REJECT so that the scanner can cope with tokens larger than its
initial buffer size.

210055ad61 here are some patches for 6.5.0 which I already submitted but have never
been applied. The patches are in the .tar.gz attachment at the end:

varchar-array.patch     this patch adds support for arrays of bpchar() and
                        varchar(), which where always missing from postgres.

                        These datatypes can be used to replace the _char4,
                        _char8, etc., which were dropped some time ago.

block-size.patch        this patch fixes many errors in the parser and other
                        program which happen with very large query statements
                        (> 8K) when using a page size larger than 8192.

                        This patch is needed if you want to submit queries
                        larger than 8K. Postgres supports tuples up to 32K
                        but you can't insert them because you can't submit
                        queries larger than 8K. My patch fixes this problem.

                        The patch also replaces all the occurrences of `8192'
                        and `1<<13' in the sources with the proper constants
                        defined in include files. You should now never find
                        8192 hardwired in C code, just to make code clearer.

cb7cbc16fa Hi, here are the patches to enhance existing MB handling. This time
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:

SET CLIENT_ENCODING TO 'encoding';

Other features include:
	Latin1 support more 8 bit cleaness

See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.
