Обсуждение: data types oid and oidvector
hey!
i wanted to know if there's a way to use the column oid (which is present in every table) as a foreign key in another table. I tried, but i couldn't do it.
and what about the type oidvector?? where can i find more information about it? i want to put in it another objetc's oids.
thanks!

It's not a good idea to use oid's as foreign keys as they may change if you dump/reload your database. For this reason, I think PostgreSQL disallows the use of them.
iirc, the oidvector column is an array of oid's type. You should look in the PostgreSQL manuals (in the pgAdmin helpfile) for more details, if not, try a post to pgsql-general@postgresql.org.
