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.
