Note: don't put any of these back till you've grokked the new code for
platform-specific comparisons that I'm about to commit...

them --- it is just *way* too painful to keep expected results in sync
when these are present.

which is broken in some weird way that I don't understand.  I think it
may be exposing a bug in the new psql --- for one thing, I get different
results when I run psql by hand than the regress script gets.  What
the heck???

code cleanup; no major improvements yet.  However, EXPLAIN does produce
more intuitive outputs for nested loops with indexscans now...

quote_postgres(...) in ecpglib.c.

The code in CVS reads:

quote_postgres(char *arg, int lineno)
{
 char    *res = (char *) ecpg_alloc(2 * strlen(arg) + 3, lineno);
 int   i,
    ri = 0;

 if (!res)
  return (res);

 res[ri++] = '\'';
 for (i = 0, ri=0; arg[i]; i++, ri++)
 {
  switch (arg[i])
  {
   case '\'':
    res[ri++] = '\'';
    break;
   case '\\':
    res[ri++] = '\\';
    break;
   default:
    ;
  }

The problem here is that ri is reset to 0, thus overwriting the initial
quote.

if presented an uninitialized (all zeroes) page.  The system no longer
crashes hard if an all-zeroes page is present in a relation.  There seem
to be some boundary conditions where a page will be appended to a relation
and zeroed, but its page header is never initialized; until we can track
down and fix all of those, robustness seems like a good idea.
Also, clean up some obsolete and downright wrong comments.

as well as when inserting entries into an existing index.

without answer. I want continue with to_char(), but I need any answer
for this patch. Please.

Thank! (and sorry of my impatient :-)

Update output to new psql conventions.

Remove older "::" type coersion syntax in favor of extended SQL92 style.
Include a few new tests for datetime/timespan arithmetic.

 rather than the Postgres "::" notation.
All of these tests have been completely inspected and give correct results.

1) datetime_pl_span() added the seconds field before adding the months
 field.  This lead to erroneous results for e.g.
   select datetime '1999-11-30' + timespan '1 mon - 1 sec';
 Reverse the order of operations to add months first.
2) tm2timespan() did all intermediate math as integer, converting to double
 at the very end. This resulted in hidden overflows when given very large
 integer days, hours, etc. For example,
   select '74565 days'::timespan;
 produced the wrong result. Change code to ensure that doubles are used
 for intermediate calculations.

to be Y2K safe.

by continuing to increment the rightmost character until we get a string
that is demonstrably greater than the pattern prefix.

<= and >= indexquals from a LIKE even if the index in question didn't
support those operators.  (As, for example, a hash index does not.)

sequence doesn't exist.

during InitProcessingMode and the CurrentTransactionState was neither
TRANS_DEFAULT nor TRANS_DISABLED.  Unfortunately, after someone's recent
change to start the transaction manager earlier in startup than it used
to be started, that caused an abort() and consequent database system
reset on quite harmless errors (such as rejecting an invalid user name!).
As far as I can see, the test on CurrentTransactionState was completely
useless anyway, so I've removed it.
