I finally got around to schlepping through pg_dump, to finish what I started
about three months (or more) ago. Attached is a gzipped diff file to apply
in the bin/pg_dump directory. This should remove all string length
dependencies, except one, which I'm working on. It has been through some
rudimentary unit testing, but that's about it, so if any of you would give
it a more strenuous run-through, I'd be grateful for the feedback.
Cheers...

SELECT null::text;
SELECT int4fac(null);
work as expected now. In some cases a NULL must be surrounded by
parentheses:
SELECT 2 + null; fails
SELECT 2 + (null); OK
This is a grammatical ambiguity that seems difficult to avoid. Other
than that, NULLs seem to behave about like you'd expect. The internal
implementation is that NULL constants are typed as UNKNOWN (like
untyped string constants) until the parser can deduce the right type.

a ".pgc " extension. The second patch fixes a coredump when there is
more than one input file (in that case, cur and types were not set to
NULL before processing the second f ile)
The patch below modifies the accepted grammar of ecpg to accept
FETCH [direction] [amount] cursor name
i.e. the IN|FROM clause becomes optional (as in Oracle and Informix).
This removes the incompatibility mentioned in section "Porting From
Other RDBMS Packages" p169, PostgreSQL Programmer's Guide. The grammar
is modified in such a way as to avoid shift/reduce conflicts. It does
not accept the statement "EXEC SQL FETCH;" anymore, as the old grammar
did (this seems to be a bug of the old grammar anyway).
This patch cleans up the handling of space characters in the scanner;
some patte rns require \n to be in {space}, some do not. A second fix is
the handling of cpp continuati on lines; the old pattern did not match
these. The parser is patched to fix an off-by-one error in the #line
directives. The pa rser is also enhanced to report the correct location
of errors in declarations in the "E XEC SQL DECLARE SECTION". Finally,
some right recursions in the parser were replaced by left-recursions.
This patch adds preprocessor directives to ecpg; in particular
EXEC SQL IFDEF, EXEC SQL IFNDEF, EXEC SQL ELSE, EXEC SQL ELIF and EXEC SQL ENDIF
"EXEC SQL IFDEF" is used with defines made with "EXEC SQL DEFINE" and
defines, specified on the command line with -D. Defines, specified on
the command line are persistent across multiple input files. Defines can
be nested up to a maximum level of 128 (see patch). There is a fair
amount of error checking to make sure directives are matched properly. I
need preprocessor directives for porting code, that is written for an
Informix database, to a PostgreSQL database, while maintaining
compatibility with the original code. I decided not to extend the
already large ecpg grammar. Everything is done in the scanner by adding
some states, e.g. to skip all input except newlines and directives. The
preprocessor commands are compatible with Informix. Oracle uses a cpp
replacement.

with DEC C.
DEC C doesn't handle double values greater than DBL_MAX, but some
PostgreSQL geo functions assign greater than DBL_MAX values to some vars
in some special cases - that couses SIGFPE. I dunno if that is the only place
to fix to work well with DEC C.

rather than returning a NaN for bogus input to pow(). Namely, HPUX 10.20.
I think this is sufficient evidence for what I thought all along, which
is that the float.c code *must* look at errno whether finite() exists or
not.

i tried it... it seems to work
