oid
--------
561644
(1 row)
afaics it seems weird.... does this mean that another postgresql
object screw up? this is the "\d nominativi" output:
Table "public.nominativi"
Column | Type | Modifiers
------------+------------------+-----------
nome_cogno | character(70) |
indirizzo | character(40) |
cap | character(5) |
citta | character(35) |
prov | character(2) |
prefisso | character(4) |
telefono1 | character(13) |
telefono2 | character(13) |
note | character(100) |
idpersona | integer |
estrazione | date |
num_estra | integer |
occupato | boolean |
cod_prov | integer |
cod_com | integer |
cod_reg | integer |
capoluo | integer |
rand | double precision |
Indexes:
"citta1_idx" btree (prov, citta) WHERE (((prov = 'BL'::bpchar) OR (prov =
'PD'::bpchar) OR (prov = 'RO'::bpchar) OR (prov = 'VE'::bpchar) OR (prov = 'TV'::bpchar)
OR (prov = 'VR'::bpchar)) AND (cod_com IS NULL))
"cod_com_ndx1" btree (cod_com)
"codprov_capo_rand1" btree (cod_prov, capoluo, rand)
"pre_tel_index1" btree (prefisso, telefono1)
and none of nominativi's indexes has an oid like 201327173
select oid
from pg_class
where relname in ('citta1_idx','cod_com_ndx1','codprov_capo_rand1','pre_tel_index1');
oid
----------
46788374
40916657
40916656
40916658
(4 rows)
> select relname from pg_class where oid = 201327173;
relname
---------
(0 rows)
while if I "ask" for oid 561644 this is what I get:
select relname from pg_class where oid = 561644;
relname
------------
nominativi
(1 row)

from what I can see from REINDEX man page, I can reindex shared system catalogs
in stand-alone mode
