PostgreSQL counterpart to DBMS_METADATA?

От

I would like to extract the DDL to create a given object (tables, primarily) from the catalog. Is there an interface,
query,etc. that will do this? I'd rather not craft the DDL myself. 

Thanks,
Mike

DDL isn't actually stored in the catalogs anywhere; it has to be
reconstructed.  The only complete solution to that problem is embodied
in pg_dump.  Hence the short answer is "extract what you need from
pg_dump output".  Depending on exactly what you need, you might be able
to get pg_dump to emit only the object definition(s) you want in the
first place.  Another possibility that wouldn't involve editing a large
dump file is to dump to an archive file and then use pg_restore's -l
and -L options to obtain a customized selective restore script.
