Hi all,
as I could not find the reason in the source code, can someone tell me why the OID counter jumps by 3 between two create table statements?
postgres=# create table t1 ( a int );
CREATE TABLE
postgres=# create table t2 ( a int );
CREATE TABLE
postgres=# select oid,relname from pg_class where relname in ('t1','t2');
oid | relname
-------+---------
16453 | t1
16456 | t2
(2 rows)
These seems not to happen with other objects, e.g. namespaces:
postgres=# create schema a;
CREATE SCHEMA
postgres=# create schema b;
CREATE SCHEMA
postgres=# select oid,nspname from pg_namespace where nspname in ('a','b');
oid | nspname
-------+---------
16459 | a
16460 | b
(2 rows)
... or indexes:
postgres=# select oid,relname from pg_class where relname in ('i1','i2');
oid | relname
-------+---------
16461 | i1
16462 | i2
I'd run this, and see if the results answer the question:
select oid,relname, reltype from pg_class where oid between 16453 and 16455;
