Are the SQL, Postgres OIDs are dyanamic or static

Question

I'm new to Postgres OIDs. I want to know, wre the SQL, Postgres OIDs are dynamic or static? Means after creating OIDs is there any possibility to change them automatically or manually?

Answer 1

PostgreSQL OID is static, but it will not survive dumping and restoring the database, so you should NOT rely on it.

Actually, in PostgreSQL 8.1 and later, configuration parameter default_with_oids is false by default, which means that unless you use CREATE TABLE using WITH OIDS option, OIDs will NOT be present in your table.

So, long story short - OIDs are thing of the past. Do not use it, do not rely on it, forget about it.
