PostgreSQL version: 7.4

Operating system: suse linux 8.2

Description: PQfinish hangs

Details:

I'm having some problems using libpq:

Some details:
OS: Suse Linux 8.2
Postgres version 7.4

The Server and client are at the same machine.

I made a connection to the Backend Server using libpq. Establish some
query's. Everything works fine. At end of my program I made a PQfinish.
Sometime's the system hangs in PQfinish !

snip:
if(db->pg_conn != NULL){
ConnStatusType = PQstatus(db->pg_conn);
if(ConnStatusType == CONNECTION_OK){
fprintf(stderr,"vor PQfinish\n\r");
PQfinish(db->pg_conn);
fprintf(stderr,"nach PQfinish\n\r");
}else{
(void)strcpy(dvs_info.subr, "PG_SQL_DENDE");
dvs_info.code = ConnStatusType;
(void)strcpy(dvs_info.sql_cmd, "PQfinish");
(void)strcpy(dvs_info.text, "Fehler bei PQstatus");
dvs_log_error();
}
db->pg_conn = NULL;
}

Any help or ideas greatly appreciated,

Walter
