Query failed: ERROR: Unable to identify an operator '=' for types 'character varying' and 'character'

Hello everybody,

I'm working with a monitoring tool for Grid enviroments. The thing is
that, this tool (GridICE) works uses a PosgreSQL Database. I get an
error at this part of the code:

--------------------------------------------------------------------
$siteName = $_GET["siteName"];
$VOName = $_GET["VOName"];
$status = $_GET["status"];
$d_start = $_GET["d_start"];
$d_start_cb = $_GET["d_start_cb"];
$d_stop = $_GET["d_stop"];
$d_stop_cb = $_GET["d_stop_cb"];
$offset = $_GET["offset"];
$cr = $_GET["cr"];

$fixedJobsOpt = $_GET["fixed"];

$offset_next = $offset+$NUM_JOBS_PER_PAGE;
$offset_prev = $offset-$NUM_JOBS_PER_PAGE;

if($d_start_cb!='true')$d_start=0;
if($d_stop_cb!='true')$d_stop=0;

$fixedJobs = 'false';
if ($fixedJobsOpt == 'on') {$fixedJobs = 'true';}

//***************** start table center ******************
$sql="select
\"LocalID\",\"Name\",\"GlobalID\",\"JobStatus\",\"LocalOwner\",\"ExecutionTarget\",\"CPUTime\",\"WallTime\",\"ExitStatus\",\"CreationTime\",\"StartTime\",\"EndTime\",\"RAMUsed\",\"VirtualUsed\",\"Group\",\"VOName\",\"GlobalOwner\"
from \"getJobDetail\"('$siteName','$VOName','$status', $fixedJobs,
".convert_date_str_dateSec($d_start).",".convert_date_str_dateSec($d_stop).",$NUM_JOBS_PER_PAGE+1,$offset)";

echo $sql;

if($d_start=='')$d_start=(date("d")-1).date("/m/Y-H:i");
if($d_stop=='')$d_stop=date("d/m/Y-H:i");
//echo $sql;
$rs = pg_query ($conn, $sql); -----> line 76
$getSiteVoJob=array();

$i=0;
while ($row = pg_fetch_row($rs)) { ---------> line 71
$getSiteVoJob[$i]=$row;
$i++;
}

$getSiteVoJobSize=sizeof($getSiteVoJob);

-----------------------------------------------------------------------------------------------------------------

The error that I get is the following one:

*Warning*: pg_query(): Query failed: ERROR: Unable to identify an
operator '=' for types 'character varying' and 'character' You will have
to retype this query using an explicit cast . in
*/var/www/html/gridice/site/jd.php* on line *67*

*Warning*: pg_fetch_row(): supplied argument is not a valid PostgreSQL
result resource in */var/www/html/gridice/site/jd.php* on line *71

D*oes anyone how to solve it?

Cheers,
