PostgreSQL version: 8.1.0
Operating system: Linux
Description: Error switching connection in embedded PostgreSQL
program
Details:
We have problem on switching connection in PostgreSQL 8.1.0 database. Here a
test case:
#include <stdio.h>
main ()
{
EXEC SQL BEGIN DECLARE SECTION;
EXEC SQL END DECLARE SECTION;
EXEC SQL CONNECT TO tcp:postgresql://localhost/basedati1 AS connection1
USER root;
EXEC SQL CONNECT TO tcp:postgresql://localhost/basedati2 AS
connection2 USER root;
EXEC SQL SET CONNECTION connection1; (*)
EXEC SQL DISCONNECT connection1;
EXEC SQL DISCONNECT connection2;
}
We have syntax error when compiling this example with ecpg at line (*)
(this is the syntax used in 8.1 documentation).
If we write
#include <stdio.h>
main ()
{
EXEC SQL BEGIN DECLARE SECTION;
EXEC SQL END DECLARE SECTION;
EXEC SQL CONNECT TO tcp:postgresql://localhost/basedati1 AS connection1
USER root;
EXEC SQL CONNECT TO tcp:postgresql://localhost/basedati2 AS connection2
USER root;
EXEC SQL SET CONNECTION TO connection1;
EXEC SQL DISCONNECT connection1;
EXEC SQL DISCONNECT connection2;
}
we haven't compiling errors but we obtain [4-1] ERROR: unrecognized
configuration parameter "connection" in PostgreSQL logs.
Thanks in advance
