Error messages may be overwritten by internal PostgreSQL (libpq) function calls. It may not return an appropriate error message if multiple errors occur inside a PostgreSQL module function. Use pg_result_error(), pg_result_error_field(), pg_result_status() and pg_connection_status() for better error handling. Note: This function used to be called pg_errormessage().

You can get the error description with pg_last_error() Something like this: $result = pg_query_params ( $dbconn, 'DELETE FROM questions WHERE question_id = $1', array ( $question_id ) ); if ($result === false) { print pg_last_error($dbconn); } else { print 'everything was ok'; } So, basically, every time you use a pg_* function, you need to check whether false was returned, that's just the way it is with those functions. Yes, you can build your own wrappers so instead of pg_query* you call my_db_query(), which then does the return value checking and exception throwing. Or, you could go with PDO, which is able to throw you PDOException for all the errors that can occour. share|improve this answer edited Sep 3 '09 at 19:33 answered Sep 3 '09 at 19:09 Anti Veeranna 8,46543157 You mean I could catch pg_last_error without explicit throw-statement? –hhh Sep 3 '09 at 19:12 More about the function: us.php.net/manual/en/function.pg-last-error.php –hhh Sep 3 '09 at 19:

Error Message Warning: pg_connect() [function.pg-connect]: Unable to connect to PostgreSQL server: FATAL: password authentication failed for user "test" in /home/test/public_html/QueueManager/Modules/Database.php on line 41 After if showing error as table format. After executing pg_connect() throwed exception. But is is not working. Code function connect() { $HOST = $GLOBALS[Database_Conn][Db_Host]; # Host name $USER = $GLOBALS[Database_Conn][Db_User]; # database user name $DBNAME = $GLOBALS[Database_Conn][Db_Name]; # name of the database $PASSWORD = $GLOBALS[Database_Conn][Db_Pass]; # password the database user. try { $conn = pg_connect("host=$HOST dbname=$DBNAME user=$USER ".
