Thread: operator commutator

Hi all,
when trying to restore a dump I get the following error:
pg_restore: [archiver (db)] could not execute query: ERROR:  argument of commutator must be a name

Operator commutator is itself, and when reading the ascii version
of the dump (produced with -Fc) I see that this has been changed
with what was probably it's oid instead.

Is this a bug in pg_dump ?
How do I tell which pg_dump version produced the dump ?
Is self commutation valid ?

TIA

Can you paste that ascii from the dump?

I'm not sure it is possible.  If it is, it will be at the very top of 
the ascii version.

CREATE OPERATOR ~= (   PROCEDURE = geometry_same,   LEFTARG = geometry,   RIGHTARG = geometry,   COMMUTATOR = 2663954,
RESTRICT = eqsel,   JOIN = eqjoinsel
 
);

No luck. Would be helpful IMO.

How about:

\x
SELECT oid, * FROM pg_operator WHERE oprname='~=' OR oid=2663954;

Unfortunately I'm not on the machine from which the dump was
issued, so I can't check. I'll inspect when possible, so I'll also
tell you which pg_dump version was it.
