Hi everyone,
Is is possible to add handlers so that a C function is fired when a transaction
is committed or rolled back, for example (pseudo code):
BEGIN;
CALL my_function(1);
CALL my_function(2);
CALL my_function(3);
ROLLACK;
my_function()
Create my_file.txt.tmp

Hi people,
after a two days break:
I could compile the following code with Visual C++ Express 2010 under Windows

#define _USE_32BIT_TIME_T

But I guess I still did something wrong, because no matter how many

Why the conditional compilation of PG_MODULE_MAGIC?
That's the recommendation, so the module compiles on all versions of
Postgres.

Thanks for reply Tom!
I've tried several version:

#include postgres.h
#include fmgr.h
#include executor\spi.h
/*
#ifdef PG_MODULE_MAGIC
PG_MODULE_MAGIC;

Thanks, I've already tried that. I doesn't make any difference. Still the same
error.
in Visual C++ I can't even compile it, although I set all links and compiler
directories like it was told in this post:
http://www.postgresql.org/docs/8.2/interactive/xfunc-c.html
I don't have more ideas.

hm. I wonder if this is confusion between value/reference datums. Can
you do a quick check to see exactly where it's crashing (either before
you get into the function, at the getarg, or in the return)?
you can elog(WARNING, msg) to print out debug info from inside the
function.

*If you're developing under nix* then I would use windows cygwin (bash

\cygwin\cygwin.bat
cd /
find . -name strings.h
you will see /usr/include
but this version of strings.h only includes string.h
to bring into environment make sure you include the /usr/include in .profile

Are you building with the same compiler as the backend was built with? If
you're using the binary distribution that means mingw unless you're testing the
pre-beta snapshot Dave uploaded a few days ago.
