In versions before PHP 4.2.0 the syntax of this function was different, see the following definition:
int pg_lo_import ( string pathname [, resource connection])The pathname argument specifies the pathname of the file to be imported as a large object. It returns FALSE if an error occurred, oid of the just created large object otherwise.
To use the large object (lo) interface, it is necessary to enclose it within a transaction block.
Nota: Cuando safe-mode (modo-seguro) está activado, PHP comprueba si el fichero(s)/directorios que vas a utilizar, tienen la misma UID que el script que está siendo ejecutado.
Nota: This function used to be called pg_loimport().
See also pg_lo_export() and pg_lo_open().
