996659f255 Fix handling of type tuple associated with a temp relation. We have
to apply the tempname->realname mapping to type name lookup as well
as relation name lookup, else the type tuple will not be found when
wanted.  This fixes bugs like this one:
create temp table foo (f1 int);
select foo.f2 from foo;
ERROR:  Unable to locate type name 'foo' in catalog

d03a933ec5 Fix performance problems with pg_index lookups (see, for example,
discussion of 5/19/00).  pg_index is now searched for indexes of a
relation using an indexscan.  Moreover, this is done once and cached
in the relcache entry for the relation, in the form of a list of OIDs
for the indexes.  This list is used by the parser and executor to drive
lookups in the pg_index syscache when they want to know the properties
of the indexes.  Net result: index information will be fully cached
for repetitive operations such as inserts.

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.

f2d1205322 Another batch of fmgr updates. I think I have gotten all old-style

3477957b44 Update sequence-related functions to new fmgr style. Remove downcasing,
quote-stripping, and acl-checking tasks for these functions from the
parser, and do them at function execution time instead.  This fixes
the failure of pg_dump to produce correct output for nextval(Foo)
used in a rule, and also eliminates the restriction that the argument
of these functions must be a parse-time constant.

85add42a57 I have large database and with this DB work more users and I very need
more restriction for fretful users. The current PG allow define only
NO-CREATE-DB and NO-CREATE-USER restriction, but for some users I need
NO-CREATE-TABLE and NO-LOCK-TABLE.

This patch add to current code NOCREATETABLE and NOLOCKTABLE feature:

CREATE USER username
    [ WITH
     [ SYSID uid ]
     [ PASSWORD 'password' ] ]
    [ CREATEDB   | NOCREATEDB ] [ CREATEUSER | NOCREATEUSER ]
->  [ CREATETABLE | NOCREATETABLE ] [ LOCKTABLE | NOLOCKTABLE ]
    ...etc.

 If CREATETABLE or LOCKTABLE is not specific in CREATE USER command,
as default is set CREATETABLE or LOCKTABLE (true).

 A user with NOCREATETABLE restriction can't call CREATE TABLE or
SELECT INTO commands, only create temp table is allow for him.

e3059fc0f5 Gen_fmgrtab.sh is strange: it is a platform dependent way (because it uses
CPP) to create platform independent files. Unfortunately, that means that
every config.status (or configure) run invariably causes a relink of the
postmaster and also that we can't put these files in the distribution
(usefully). So we make it a little smarter: when the output files already
exist and it notices that it would recreate them in identical form, it
doesn't touch them. In order to avoid re-running the make rule all the time
we update a timestamp file instead.

Update release_prep accordingly. Also make Gen_fmgrtab.sh use the awk that
is detected at configure time, not necessarily named `awk' and have it check
for exit statuses a little better.

In other news... Remove USE_LOCALE from the templates, it was set to `no'
everywhere anyway. Also remove YACC and YFLAGS from the templates, configure
is smart enough to find bison or yacc itself. Use AC_PROG_YACC for that
instead of the hand-crafted code. Do not set YFLAGS to `-d'. The make rules
that need this flag should explicitly invoke it. YFLAGS should be a user
variable. Update the makefiles to that effect.

05cd91a582 typeTypeName() must return a pstrdup'd copy of the type name, not a
direct pointer into the syscache entry for the type.  In some cases
the syscache entry might get flushed before we are done using the
returned type name.  This bug accounts for difficult-to-repeat
failures seen when INSERTs into columns of certain data types are
run in parallel with VACUUMs of system tables.  There may be related
problems elsewhere --- we need to take a harder look at uses of
syscache data.

48165ec226 Latest round of fmgr updates. All functions with bool,char, or int2
inputs have been converted to newstyle.  This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters.  Still
more to do for the Alpha port however.

6a68f42648 The heralded `Grand Unified Configuration scheme' (GUC)
That means you can now set your options in either or all of $PGDATA/configuration,
some postmaster option (--enable-fsync=off), or set a SET command. The list of
options is in backend/utils/misc/guc.c, documentation will be written post haste.

pg_options is gone, so is that pq_geqo config file. Also removed were backend -K,
-Q, and -T options (no longer applicable, although -d0 does the same as -Q).

Added to configure an --enable-syslog option.

changed all callers from TPRINTF to elog(DEBUG)

0a7fb4e918 First round of changes for new fmgr interface. fmgr itself and the
key call sites are changed, but most called functions are still oldstyle.
An exception is that the PL managers are updated (so, for example, NULL
handling now behaves as expected in plperl and plpgsql functions).
NOTE initdb is forced due to added column in pg_proc.

ff566b2241 Modify raw parsetree representation returned by gram.y for SubLinks:
the oper field should be a valid Node structure so it can be dumped by
outfuncs.c without risk of coredump.  (We had been using a raw pointer
to character string, which surely is NOT a valid Node.)  This doesn't
cause any backwards compatibility problems for stored rules, since
raw unanalyzed parsetrees are never stored.

bb7e5dc2c0 Tweak TypeCategory to treat new BIT types as of STRING category, rather
than not knowing what they are at all.  Perhaps they should have their own
type category?  Hard to say.  In the meantime, doing it this way allows
SELECT 'unknown' || 'unknown' to continue being resolved as textcat,
instead of spitting out an ambiguous-operator error.

Add a random number generator and seed setter (random(), SET SEED)
Fix up the interval*float8 math to carry partial months

2dabd2cd1f Allow full type names in CREATE FUNCTION arguments and return type.
Move CREATE FUNCTION/WITH clause to end of statement to get around
 shift/reduce conflicts with type names containing "WITH".
Add lots of tokens as allowed ColId's and/or ColLabel's,
 so this should be a complete set for the v7.0 release.

5c462baebc transformCreateStmt should put Ident nodes, not ColumnDef nodes, into
keys lists of Constraint nodes.  This eliminates a type pun that would
probably have caused trouble someday, and eliminates circular references
in the parsetree that were causing trouble now.
Also, change parser's uses of strcasecmp() to strcmp().  Since scan.l
has downcased any unquoted identifier, it is never correct to check an
identifier with strcasecmp() in the parser.  For example,
	CREATE TABLE FOO (f1 int, UNIQUE("F1"));
was accepted, which is wrong, and xlateSqlFunc did more than it should:
select datetime();
ERROR:  Function 'timestamp()' does not exist
(good)
select "DateTime"();
ERROR:  Function 'timestamp()' does not exist
(bad)

a73b75615f transformExpr() did the Wrong Thing if applied to a SubLink node that
had already been transformed.  This led to failure in examples like
UPDATE table SET fld = (SELECT ...).  Repair this, and revise the
comments to explain that transformExpr has to be robust against this
condition.  Someday we might want to fix the callers so that
transformExpr is never invoked on its own output, but that someday
is not today.

440b0fea3d Another go-round with resolution of ambiguous functions and operators.
In function parsing, try for an actual function of the given name and
input types before trying to interpret the function call as a type
coercion request, rather than after.  Before, a function that had the
same name as a type and operated on a binary-compatible type wouldn't
get invoked.  Also, cross-pollinate between func_select_candidates and
oper_select_candidates to ensure that they use as nearly the same
resolution rules as possible.  A few other minor code cleanups too.

d63e05a638 Improve error message wording in unary_op_error() --- suggest that
problem could be lack of parentheses.  This addresses cases like
X UserOp UserOp Y, which will be parsed as (X UserOp) UserOp Y,

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.

d14c8aab99 Turns out that Mazurkiewicz's gripe about 'function inheritance' is
actually a type-coercion problem.  If you have a function defined on
class A, and class B inherits from A, then the function ought to work
on class B as well --- but coerce_type didn't know that.  Now it does.
