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

initdb. No more obscure dependencies on environment variables or paths.
It
now finds the templates and the right postgres itself (with cmd line
options as fallback). It also no longer depends on $USER (su safe), and
doesn't advertise that --username allows you to install the db as a
different user, since that doesn't work anyway. Also, recovery and
cleanup
on all errors. Consistent options, clearer documentation.
Please take a look at this and adopt it if you feel it's safe enough. I
have simulated all the stupid circumstances I could think of, but you
never know with shell scripts.
Oh yeah, you can give the postgres user a default password now.

I sending promised patch with:
* getopt_long() - for pg_dump (portable)
* and "Usage: " changes in scripts in src/bin/
- this changes are cosmetic only, not change any
feature ...etc.
All PostgreSQL routines (scripts) support now long options and
help's output is alike for all scripts and all support -? or --help.

OK, good point. I tried to implement it somewhere else and ended up
extending transformAttr. Attached you'll find the patch.

didn't have time for documentation yet, but I'll write some. There are
still some things to work out what happens when you alter or drop users,
but the group stuff in and by itself is done.

equality. The lobits macro is wrong and extracts the wrong set of
bits out of the structure.
To exhibit the problem:
select '000000:000000'::macaddr = '000000:110000'::macaddr ;
?column?

Oops, I got crossed up with Jan's improvements. Ignore this.
