PostgreSQL uses a hidden "oid" field to uniquely identify all records
across all tables in all databases on a particular server. On my
platform, this number is an unsigned 32-bit integer, meaning 0 to about 4
billion.
1. This implies a hard limit of 4 billion records on a server, right?
2. When I delete records, are those oids ever reused?
