Description: ecpg doesn't like "inet" operator
Details:

This is a sample of my C programm resuming the problem :

***************************************************
#include <stdio.h>
#include <stdlib.h>

int main()
{
EXEC SQL BEGIN DECLARE SECTION;

char *ip_address = "192.168.1.2";
char ip_result[20];

EXEC SQL END DECLARE SECTION;

EXEC SQL WHENEVER SQLWARNING SQLPRINT;

EXEC SQL CONNECT TO synch(at)localhost USER synch IDENTIFIED BY synch;

EXEC SQL SELECT text(inet :ip_address) INTO :ip_result;

EXEC SQL DISCONNECT;

printf("ip_result: %s\n", ip_result);

return EXIT_SUCCESS;
}

***************************************************

And ecpg returns :
test_sql.pgc:17: ERROR: syntax error at or near ":ip_address"

This error correpond with "EXEC SQL SELECT inet :ip_address;". If I remove
inet operator it works well. Of course text() does nothing when I remove
inet as postgres doesn't now it is an IP address.
