First step in cleaning up backend initialization code.
Fix for FATAL: now FATAL is ERROR + exit.

This may solve a TODO item

heap_insert() any more. No reasons to do it, and old comments
said about this.

insert, update or delete.  It will return -1 on error, although I've yet
to an error situation to prove that out!

A few other changes, but I forget what :(

 Still need the code updated for LO examples.

display of default expressions isn't quite so ugly.

quite the same way that transformInsertStatement does, so that an expression
could be accepted by CREATE TABLE and then fail when used.  Also, put back
check that CONSTRAINT expressions must yield boolean...

expressions in CREATE TABLE.  There is no longer an emasculated expression
syntax for these things; it's full a_expr for constraints, and b_expr
for defaults (unfortunately the fact that NOT NULL is a part of the
column constraint syntax causes a shift/reduce conflict if you try a_expr.
Oh well --- at least parenthesized boolean expressions work now).  Also,
stored expression for a column default is not pre-coerced to the column
type; we rely on transformInsertStatement to do that when the default is
actually used.  This means "f1 datetime default 'now'" behaves the way
people usually expect it to.
BTW, all the support code is now there to implement ALTER TABLE ADD
CONSTRAINT and ALTER TABLE ADD COLUMN with a default value.  I didn't
actually teach ALTER TABLE to call it, but it wouldn't be much work.

--enable-debug adds -g (unconditionally)
--disable-debug removes -g (if it was already in there somehow)
(giving neither does nothing)

Since none of the templates default CFLAGS with a -g you're not likely
to
end up with two -g flags. Not that they'd hurt though.

It doesn't do anything about C++.

make it call eval_const_expressions() so that it doesn't have to know).

not just C, so that ISCACHABLE attribute can be specified for user-defined
functions.  Get rid of ParamString node type, which wasn't actually being
generated by gram.y anymore, even though define.c thought that was what
it was getting.  Clean up minor bug in dfmgr.c (premature heap_close).

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

modifyAggrefQual.  This routine really, really needs to be retired, but
until we have subselects in FROM there's no chance of doing the job right.
In the meantime try to respond to unhandlable cases with elog rather than
coredump.

in the Expr nodes they produce.  This fixes a few cases of errors like
'typeidTypeRelid: Invalid type - oid = 0' caused by calling parser-related
routines on expression trees that have already been processed by planner-
related routines.

they have no hardwired limit on the length of a rule's text.  Fix a couple
of minor bugs in passing --- deparsed UPDATE queries didn't have quotes
around relation name, and quotes and backslashes in constant values weren't
backslash-quoted.

 Seems to read better this way...

 committed, but will be within a week or two).
Actually include the reference page into the docs...

 the Programmer's Guide.

expression_tree_mutator rather than ad-hoc tree walking code.  This shortens
the code materially and fixes a fair number of sins of omission.  Also,
change modifyAggrefQual to *not* recurse into subselects, since its mission
is satisfied if it removes aggregate functions from the top level of a
WHERE clause.  This cures problems with queries of the form SELECT ...
WHERE x IN (SELECT ... HAVING something-using-an-aggregate), which would
formerly get mucked up by modifyAggrefQual.  The routine is still
fundamentally broken, of course, but I don't think there's any way to get
rid of it before we implement subselects in FROM ...
