Hi All;
I want to dump a set of BLOB's from one db/server and import to another.
I assume I cannot do a pg_dump unless I also dump related
pg_largeobject rows for the referenced OID
I assume I'll need to export via distinct lo_export commands and use
lo_import to insert into the second database server.
Is there a way to do a bulk transfer or export/import of lo_* style
large objects ?
Thanks in advance

Why don't you just use pg_dump?

pg_dump should dump large objects automatically. If you're dumping a
single table, make sure you use the -b switch. Saith the manpage
-b
--blobs
Include large objects in the dump. This is the default behavior
except when --schema, --table, or --schema-only is specified, so
the -b switch is only useful to add large objects to selective
dumps.
