its not very clear if pg_lo_import needs to have pg_lo_open called first. Because pg_lo_import handles the process of writign to the file, it seems logical that pg_lo_open does not need to be called. However due to the ugly nature of how postgres handles oid objects, it would be nice to have this documented.

(PHP 4 >= 4.2.0, PHP 5)
pg_lo_import — Import a large object from file
Popis
int pg_lo_import ( resource $connection, string $pathname )int pg_lo_import ( string $pathname )
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] )pg_lo_import() creates a new large object in the database using a file on the filesystem as its data source.
To use the large object interface, it is necessary to enclose it within a transaction block.
Poznámka: Pokud je zapnut bezpečný režim (safe-mode), PHP kontroluje, zda soubory/adresáře, se kterými pracujete, mají stejné UID jako spuštěný skript.
Poznámka: This function used to be called pg_loimport().
Seznam parametrů
- connection
PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().
- pathname
The full path and file name of the file on the client filesystem from which to read the large object data.
Návratové hodnoty
The OID of the newly created large object, or FALSE on failure.

Due to a bug, OLD API does not available with PHP 4.2.0 and 4.2.1.
PHP 4.2.2 will support OLD API again and will be kept long enough.
New API will be available PHP 4.2.0 to later versions.

Due to a bug, PHP 4.2.0 and 4.2.1 does not support pg_lo_import() old API. It's fixed in PHP 4.2.2.
BTW, new API will be always available from PHP 4.2.0 to later versions. Older API will be kept long enough, also.
