( resource connection, string pathname )
( string pathname )
In versions before PHP 4.2.0 the syntax of this function was different,
see the following definition:
( string pathname [, resource connection] )
pg_lo_import() creates a new large object
in the database using a file on the filesystem as its data
To use the large object interface, it is necessary to
enclose it within a transaction block.
Note: When safe mode is enabled, PHP checks whether
the files or directories you are about to operate on have the same UID (owner) as the
script that is being executed.
This function used to be called pg_loimport().
