pg_lo_export
pg_lo_export takes a large object in a PostgreSQL database and saves its contents to a file on the local filesystem.
To use the large object interface, it is necessary to enclose it within a transaction block.
Note:
This function used to be called pg_loexport.
Parameters
- connection
-
An PgSql\Connection instance. When connection is unspecified, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.
Warning:
As of PHP 8.1.0, using the default connection is deprecated.
- oid
-
The OID of the large object in the database.
- pathname
-
The full path and file name of the file in which to write the large object on the client filesystem.
Return Values
Returns true on success or false on failure.
