Обсуждение: Do the datatypes have set id/oid that are constant?

Hi,

I was wandering if the oid's for the datatypes are the same for every
installation of postgres?

Built-in datatypes will have the same OIDs in every installation of a
given version (and, in practice, they generally don't change across
versions either).  Types created after initdb will have variable OIDs.
