FW: About OIDs

They are invisible unless you ask to see them:

C:\CONNX32\CONNXSTORE\BIN>psql -h localhost connxdatasync
Welcome to psql, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

connxdatasync=# select * from pg_amop limit 1;
amopid | amopclaid | amopopr | amopstrategy
--------+-----------+---------+--------------
402 | 422 | 493 | 1
(1 row)

connxdatasync=# select Oid, * from pg_amop limit 1;
oid | amopid | amopclaid | amopopr | amopstrategy

Hi, Alvaro,
Thank you for your reply. Well, if you view the system defination from
PgAdminII 1.4.12, you will see the following one example which shows
that no OIDs. I am not sure whether PgadminII is right or you are right
on this topic.

-- Table: pg_amop

CREATE TABLE pg_amop (
amopclaid oid,
amopstrategy int2,
amopreqcheck bool,
amopopr oid,
CONSTRAINT pg_amop_opc_opr_index UNIQUE (amopclaid, amopopr),
CONSTRAINT pg_amop_opc_strategy_index UNIQUE (amopclaid, amopstrategy)
) WITHOUT OIDS;
