Обсуждение: Removing OIDs without recreate
Hi, I'm winder if I can change the clause 'WITH OIDS' to 'WITHOUT OIDS' on a table without recreating it (eg. usong ALTER TABLE). The problem is that my tables are very big, and I do not need the OIDs at all. It was a mistake to create them with OIDs. Is there any way to correct it. Does it make any sense? Can it run out of OIDs during time? many thanks, -- Csaba Együd --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Using 'ALTER TABLE tablename SET WITHOUT OIDS;' command it rises an error saying 'ERROR: parser: parse error at or near "set" at character 23' What is wrong with it? -- Csaba --- Outgoing mail is certified Virus Free.

cygwin/7.3.4 The doc contains the option but doesn't work - at least for me. --Csaba > -----Original Message----- > From: Karel Zak [mailto:zakkr@zf.jcu.cz] > Sent: 2004. május 7. 13:48 > To: Együd Csaba > Cc: 'Pgsql-General@Postgresql.Org (E-mail)' > Subject: Re: [GENERAL] Removing OIDs without recreate > > > On Fri, May 07, 2004 at 01:13:52PM +0200, Együd Csaba wrote: > > Using 'ALTER TABLE tablename SET WITHOUT OIDS;' command it > > rises an error saying > > 'ERROR: parser: parse error at or near "set" at character 23' > > What is wrong with it? > > Which PostgreSQL version do you have? > > Karel > > -- > Karel Zak <zakkr@zf.jcu.cz> > http://home.zf.jcu.cz/~zakkr/ > --- > Incoming mail is certified Virus Free. > Checked by AVG anti-virus system (http://www.grisoft.com). > Version: 6.0.677 / Virus Database: 439 - Release Date: 2004. 05. 04. > --- Outgoing mail is certified Virus Free.

Sorry I made a mistake, I saw docs for 7.4, because I use an other server running that version. So this won't work on 7.3.*. Can I drop OID column painlessly? Does it lead to any problems?
