I'm trying to insert a lob into a pgsql field.
My first problem is that the documentation doesn't say if the table field should be a bytea or an oid (more suitable for a large object). I supposed both worked.
I've tried with a bytea and it worked as expected. But the same operation with an OID field doesn't work. 
(Also, i've noticed three undocumented public methods in pdo_pgsql (pgsqlLOBUnlink, pgsqlLOBOpen, pgsqlLOBCreate))

Shouldn't it work with both methods???

At least, the quote function escapes always the lob as if it was a bytea. But in the rest of the driver it considers the possibility of an oid.

Thanks in advance.
