get diagnostics not supported by ecpg?

Hi all,

It seems that get diagnostics is not supported by ecpg in postgresql
7.3, I always get the following error when trying to use it:

ERROR: parse error at or near "diagnostics"

For example, the following code does not compile:

#include <stdio.h>

int main()
{
EXEC SQL BEGIN DECLARE SECTION;
char msg[8191];
int msg_len=0;
EXEC SQL END DECLARE SECTION;

EXEC SQL connect to 'test';

EXEC SQL get diagnostics :msg_len=ROW_COUNT;

fprintf(stderr, "SQL: %d\n", msg_len);

EXEC SQL disconnect current;

return 0;
}

same if I use

EXEC SQL get diagnostics exception 1
:msg=MESSAGE_TEXT,
:msg_len=MESSAGE_LENGTH;

What am I doing wrong? Or it's just not supported by ecpg in 7.3?

Thanks in advance,
Slava
