Bug reference: 5464

PostgreSQL version: 8.4.4
Operating system: Linux
Description: ecpg on 64bit system converts "long long" to "long"
Details:
This applies for at least ecpg 4.5.0 and 4.4.0.
On 32 bit system the type is not changed.
Example:
----------------------------------------
EXEC SQL INCLUDE sqlca;
EXEC SQL BEGIN DECLARE SECTION;
long long test;
EXEC SQL END DECLARE SECTION;
int main(int argc, char **argv) {
return 0;
}
----------------------------------------
If you run it through ecpg, in the resulting c file
the variable test has type long on 64 bit system.
On 32 bit system it is long long.

Apparently when this code was written "long long" was 64bit, but it doesn't seem to be that way on 64bit systems nowadays. I will check to see if there is an easy fix. If it is fairly interruptive the fix won't make it into 9.0 though.

I believe on IBM Power, LONG LONG *is* 64 bit.

I'm currently without real access to a 64bit system until I come back home. If it is 64bit on *all* 64bit systems the problem is slightly different.

But the compiler throws warnings for %lld with long int type. It should not be required to change the code to not run into such warnings. Yes, I know the PRI... macros from inttypes.h ...

Just committed a patch to HEAD that hopefully fixes the problem.
