Hi,
Although I finally managed to build libpq using Visual C++, I'm
continuously experiencing problems with this IDE.
Therefore I switched to MinGW and it was indeed easy to compile libpq
with it from the first time on.
However, I'm experiencing the same problem as discussed on
Dear PostgreSQL community,
When trying to compile c++ code including libpq against the static
version libpq.lib, Visual Studio 2010 gives me the following errors:
1main.obj : error LNK2019: Unresolved external reference __imp__exit
in Funktion _main.
1libpq.lib(fe-connect.obj) : error
Thanks for your answer. I was indeed using the static libpq version from
the installer.
I tried to compile my own one with Visual Studio 2010, but this caused a
lot of problems due to the fact that Visual Studio 2010 has changed the
manifest tool.
So I built a static version using Visual C++
Thanks again for your answer.
For all those experiencing similar problems, the missing libraries were:
1) ws2_32.lib
2) secur32.lib (for the SSPI functions)
My code is compiled now without errors, but it seems to contain a buffer
overflow. So there's still some work left for me ...

My application looks like this:
#include iostream
#include libpq-fe.h
using namespace std;
int main(void)
{
PGconn *conn;
const char *info = hostaddr = 'postgres.server.com' \
port = '5432' \
dbname = 'mydb' \
user
Okay, I could fix it by myself now:
One has to tell Visual C++ to ignore msvcrt.lib.
A warning message during the compilation of my code already lamented a
conflict between msvcrt and the included libraries.
I should have taken it for serious instead of just ignoring it.
So now everything works
Dear PostgreSQL community,
Please consider the following minimal example:
CREATE TABLE example (row_id SERIAL, value TEXT);
INSERT INTO example(value) VALUES ('val1');
INSERT INTO example(value) VALUES ('val2');
INSERT INTO example(value) VALUES ('val3');
CREATE OR REPLACE FUNCTION foo()
Hello everybody out there familiar with the tablefunc module,
Having read the documentation of the tablefunc module,
I'm wondering whether it is possible to get the values for the names of
the columns for the crosstab query from a subquery.
A minimal example would look like this:
CREATE TABLE
the name of the column but of course also a
data type (always the same - int).
Is it possible for a newbie to solve my problem by a user-defined
function in PL/pgSQL or is it rather complicated?

Hello everybody out there using PostgreSQL,
After having read the official documentation and having done extensive web
search, I'm wondering how to perform something like a SELF LEFT OUTER JOIN in
PostgreSQL, i.e. a SELF JOIN on a table containing NULL values in one of the
columns to join.
Hello everybody out there using PostgreSQL,
What is the problem with the following C++ code for the extraction of
data from a BYTEA column to a binary file?
#include stdlib.h
#include stdio.h
#include iostream
#include fstream
#include libpq-fe.h
using namespace std;
main ()
{
PGconn
Hello everybody out there using PostgreSQL,
One of the tables in my database contains pictures in jpeg format in a
column of the type BYTEA.
I have written a script in Python for inserting pictures into the
database as well as exporting them from the database later. It works fine.
