Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.

For future reference, casting NULL to a pointer type is only necessary
when (a) invoking a function AND either (b) the function has no prototype
OR (c) the function is a varargs function.

parameters to be declared with names. pg_proc has a column to store
names, and CREATE FUNCTION can insert data into it, but that's all as
yet. I need to do more work on the pg_dump and plpgsql portions of the
patch before committing those, but I thought I'd get the bulky changes
in before the tree drifts under me.
initdb forced due to pg_proc change.

to be less dangerous, and often faster as well. ExprState trees are
not kept across transaction boundaries; this eliminates problems with
resource leakage in failed transactions. But by keeping them in a
per-transaction EState, we can safely arrange for a single ExprState
to be shared by all the expression evaluations done in a given plpgsql
function call. (Formerly it seemed necessary to create and destroy an
ExprState for each exec_eval_simple_expr() call.) This saves time in
any scenario where a plpgsql function executes more than one expression.
Seems to be about as fast as 7.3 for simple cases, and significantly
faster for functions that do a lot of calculations.

method. Fix a number of places where shared libraries were linked without
mentioning all the libraries they depend on; the Darwin and AIX ports
are known to require this, and it doesn't seem to hurt any other supported
platforms. (Hence, remove code in pl/tcl makefile that tried to avoid
mentioning other libs if not needed.)

one relation. This avoids crashes due to differing rowtypes for
different relations. Per bug report from Lance Thomas, 7-Feb-03.

the trigger is attached to in the hashkey. This ensures that we will
create separate compiled trees for each table the trigger is used with,
avoiding possible datatype-mismatch problems if the tables have different
rowtypes. This is essentially the same bug recently identified in plpython
--- though plpgsql doesn't seem as prone to crash when the rowtype changes
underneath it. But failing robustly is no substitute for just working.

OK; the only change in this version is "isconst = false;". Now you can
use $0 as a result placeholder if desired. E.g.:
create or replace function tmp(anyelement, anyelement) returns anyarray as '
declare
v_ret alias for $0;
v_el1 alias for $1;
v_el2 alias for $2;
begin
v_ret := ARRAY[v_el1, v_el2];
return v_ret;
end;
' language 'plpgsql';
create table f(f1 text, f2 text, f3 int, f4 int);
insert into f values ('a','b',1,2);
insert into f values ('z','x',3,4);
select tmp(f1,f2) from f;
select tmp(f3,f4) from f;

Attached is a patch that removes all of the RExec code from plpython from
the current PostgreSQL CVS. In addition, plpython needs to be changed to an
untrusted language in createlang. Please let me know if there are any
problems.

to put spaces around parameter references, as in "x<=$2". The second
change improves compatibility with Oracle and some other RDBMSes. This
was discussed and agreed to back in January, but did not get done.

yy_fatal_error() call results in elog(ERROR) not exit(). This was
already fixed in the main lexer and plpgsql, but extend same technique
to all the other dot-l files. Also, on review of the possible calls
to yy_fatal_error(), it seems safe to use elog(ERROR) not elog(FATAL).

performance, gives the right answer for line position in functions
containing multiline literals, suppresses annoying compiler warnings,
and generally is so much better I wonder why we didn't do it before.

rewritten and the protocol is changed, but most elog calls are still
elog calls. Also, we need to contemplate mechanisms for controlling
all this functionality --- eg, how much stuff should appear in the
postmaster log? And what API should libpq expose for it?
