memory leak occur when disconnect database

["tanjunhua" <tanjh@xxxxxxxxxx>]

I'm running postgres 8.1.8 on Debian and I think memory leak occur when
disconnect database.

1.  environment setting
1.1 postgresql version:
                                                   version
---------------------------------------------------------------------------------------------------------------
PostgreSQL 8.1.8 on i486-pc-linux-gnu, compiled by GCC cc (GCC) 4.1.2
20061115 (prerelease) (Debian 4.1.1-21)
(1 row)

1.2 kernel version:
Linux PMS 2.6.18-4-686 #2 SMP Fri Aug 1 22:47:38 JST 2008 i686 GNU/Linux

2. test example:
int OpenDataBase(void)
{
    int i_ret = 0;

    EXEC SQL CONNECT TO test_db;
    if(sqlca.sqlcode == 0){
         i_ret = 1;
    }
    return i_ret;
}

sint8 CloseDataBase(void)
{
sint8 i_ret = !0;

EXEC SQL disconnect all;
if(sqlca.sqlcode == 0){
     i_ret = 0;
}
 return i_ret;
}

int main()
{
   OpenDataBase();
   CloseDataBase();
}

when I use valgrind to check memory information, the memory leak is in view. 
would anyone give me a suggestion. I'm looking forward your help.

best wishes.
