3.20) What is an oid? What is a tid?
Oids are Postgres's answer to unique row ids or serial columns. Every
row that is created in Postgres gets a unique oid. All oids generated
by initdb are less than 16384 (from backend/access/transam.h). All
post-initdb (user-created) oids are equal or greater that this. All
these oids are unique not only within a table, or database, but unique
within the entire postgres installation.
