pg_result_error_field() returns one of the detailed error message fields associated with result
resource. It is only available against a PostgreSQL 7.4 or above server. The error field is specified by the fieldcode
.
Because pg_query() and pg_query_params() return FALSE
if the query fails, you must use pg_send_query() and pg_get_result() to get the result handle.
If you need to get additional error information from failed pg_query() queries, use pg_set_error_verbosity() and pg_last_error() and then parse the result.
A PostgreSQL query result resource from a previously executed statement.

values are: PGSQL_DIAG_SEVERITY
, PGSQL_DIAG_SQLSTATE
, PGSQL_DIAG_MESSAGE_PRIMARY
, PGSQL_DIAG_MESSAGE_DETAIL
