Обсуждение: Re: [GENERAL] trouble with pg_upgrade 9.0 -> 9.1
This is the first pg_upgrade mismatch report we have gotten about 9.1. I have asked the reporter for details. Is what is the full 9.1 version number? --------------------------------------------------------------------------- On Mon, Dec 17, 2012 at 03:33:40PM +0400, Groshev Andrey wrote: > Hello! > I'm trying to update a database from version 9.0 to 9.1 by pg_upgrade. > The test is normal, but the actual conversion fails. > This is a bug from pg_upgrade? > I just saw this in the newsletter similar error with a note that it has been fixed in 9.1.2, but I already install 9.1.7. > > My environment > centos 6.3 > #

I am now confused over the error message above. This is the code that
is generating the error:
/* * TOAST table names initially match the heap pg_class oid. * In pre-8.4, TOAST table names
changeduring CLUSTER; in pre-9.0, * TOAST table names change during ALTER TABLE ALTER COLUMN SET TYPE. *

(strcmp(old_rel->nspname,new_rel->nspname) != 0 || ((GET_MAJOR_VERSION(old_cluster.major_version) >= 900 ||
strcmp(old_rel->nspname, "pg_toast") != 0) && strcmp(old_rel->relname, new_rel->relname) != 0))
pg_log(PG_FATAL, "Mismatch of relation names: database \"%s\", " "old rel %s.%s, new rel

new_rel->relname);
Looking at the Russian, I see 'old rel' public.lob.* and 'new rel'
public.plob.*. I assume the database is called 'database', and the
schema is called 'public', but what is 'lob' and 'plob'? If those are
tables or indexes, what is after the period? Do you have periods
embedded in the table/index names? That is certainly possible, but not
common, e.g.:
test=> create table "test.x" (y int);CREATE TABLE
Is the schema called "public.lob"? I expected to see schema.objname.

Can you post the full definition of the table on this public email list?
Also, why did the error think this was in the public schema? Any idea?

There is another table "ВерсияВнешнегоДокумента$Документ" (without ^lob.)
It is referenced by a foreign key ("rlob.ВерсияВнешнегоДокумента$Документ-@Файл")
But as I understand it, the problem with the primary key.

[ Sorry I have not been replying promptly. I have been sick with the
flue for the past four days, and while I read the email promptly, my
brain isn't sharp enough to send email out for everyone to read. I am
better today so hopefully I will be 100% soon. ]
OK, this tells me that the period is in the table name:
-- Name: lob.ВерсияВнешнегоДокумента$Документ;Type: TABLE; Schema: public; Owner: postgres; Tablespace:
I needed to check that the period wasn't a symptom of a bug.

Does the old database have a table with prefix "plob.", called
plob.ВерсияВнешнегоДокумента$Документ?
If not, if you do pg_dumpall --schema-only --binary-upgrade, is there a
table with that name mentioned?

Also, when you say "rlob" above, is the 'r' a Latin letter sound that
would look like a Russian 'p' in the error message? (In Cyrillic, a
Latin-looking p sounds like Latin-sounding r.)

No, people can confuse writing, but it makes a computer.
Unfortunately, I have not found developer this database, but I understand the logic was:
plob - primary key (lob ~ BLOB)
rlob - reference key (lob ~ BLOB)
Maybe if I describe the task, this part of the database, the problem is clear.
We need to maintain external documents (binary scans, per page).
Therefore, there is a table to store the titles and a table to store binary data.
To make it more comfortable I replaced all Russian words translated words.
This a table for headers store.
-- Table: "VersionOfTheExternalDocument$Document"
-- DROP TABLE "VersionOfTheExternalDocument$Document";
CREATE TABLE "VersionOfTheExternalDocument$Document"
( "@File" integer NOT NULL DEFAULT
nextval((pg_get_serial_sequence('"public"."VersionOfTheExternalDocument$Document"'::text,'@File'::text))::regclass),
"GUID"uuid, "DataTime" timestamp without time zone DEFAULT (now())::timestamp without time zone, "Name" character
varying,"Size" integer, CONSTRAINT "VersionOfTheExternalDocument$Document_pkey" PRIMARY KEY ("@File")
)
WITH ( OIDS=FALSE
);
ALTER TABLE "VersionOfTheExternalDocument$Document" OWNER TO postgres;
GRANT ALL ON TABLE "VersionOfTheExternalDocument$Document" TO postgres;
GRANT SELECT ON TABLE "VersionOfTheExternalDocument$Document" TO view_user;
-- Index: "iVersionOfTheExternalDocument$Document-blb_header"
-- DROP INDEX "iVersionOfTheExternalDocument$Document-blb_header";
CREATE INDEX "iVersionOfTheExternalDocument$Document-blb_header" ON "VersionOfTheExternalDocument$Document" USING btree
("GUID","@Файл", "ДатаВремя") WHERE "GUID" IS NOT NULL;
---------------------------------------------------------------
And this for data.
-- Table: "lob.VersionOfTheExternalDocument$Document"
-- DROP TABLE "lob.VersionOfTheExternalDocument$Document";
CREATE TABLE "lob.VersionOfTheExternalDocument$Document"
( "@File" integer NOT NULL, "Page" integer NOT NULL, "Data" bytea, CONSTRAINT
"lob.VersionOfTheExternalDocument$Document_pkey"PRIMARY KEY ("@File", "Page"), CONSTRAINT
"rlob.VersionOfTheExternalDocument$Document-@File"FOREIGN KEY ("@File") REFERENCES
"VersionOfTheExternalDocument$Document"("@File") MATCH SIMPLE ON UPDATE CASCADE ON DELETE CASCADE DEFERRABLE
INITIALLYIMMEDIATE
)
WITH ( OIDS=FALSE
);

GRANT ALL ON TABLE "lob.VersionOfTheExternalDocument$Document" TO postgres;

OK, now I know what is happening, though I can't figure out yet how you
got there. Basically, when you create a primary key, the name you
supply goes into two places, pg_class, for the index, and pg_constraint
for the constraint name.
What is happening is that you have a "pg_class" entry called lob.*_pkey
and a "pg_constraint" entry with plob.*. You can verify it yourself by
running queries on the system tables. Let me know if you want me to
show you the queries.
pg_dump dumps the pg_constraint name when recreating the index, while
pg_upgrade uses the pg_class name. When you restore the database into
the new cluster, the pg_class index name is lost and the new primary key
gets identical pg_class and pg_constraint names.
I tried to recreate the problem with these commands:
test=> create table test (x int primary key);NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "test_pkey"
fortable "test"CREATE TABLEtest=> alter index "test_pkey" rename to ptest;ALTER INDEXtest=> select * from pg_constraint
whereconname = 'ptest'; conname | connamespace | ---------+--------------+- ptest | 2200 | (1 row)test=>
select* from pg_class where relname = 'ptest'; relname | relnamespace | ---------+--------------+- ptest |
2200| (1 row)
As you can see, ALTER INDEX renamed both the pg_constraint and pg_class
names. Is it possible someone manually updated the system table to
rename this primary key? That would cause this error message. The fix
is to just to make sure they match.
Does pg_upgrade need to be modified to handle this case? Are there
legitimate cases where they will not match and the index name will not
be preserved though a dump/restore? This seems safe:
test=> alter table test add constraint zz primary key using index ii;NOTICE: ALTER TABLE / ADD CONSTRAINT USING INDEX
willrename index "ii" to "zz"ALTER TABLE

I have already begun to approach this to the idea, when noticed that pgAdmin describes this index through "_pkey", and
throughthe pg_dump "plob.".
But your letter immediately pointed me to the end of my research :)

Unfortunately, my knowledge is not enough to talk about it.
I do not know what comes first in this case: pg_class, pg_constraint or pg_catalog.index or pg_catalog.pg_indexes.
Incidentally, in the last of:
#
select schemaname,tablename,indexname,tablespace from pg_catalog.pg_indexes where indexname like
'%ВерсияВнешнегоДокумента$Документ%';schemaname| tablename | indexname
| tablespace
------------+--------------------------------------+----------------------------------------------+------------public

ВерсияВнешнегоДокумента$Документ | ВерсияВнешнегоДокумента$Документ_pkey |public |
ВерсияВнешнегоДокумента$Документ | iВерсияВнешнегоДокумента$Документ-blb_header |
(3 rows)
If pg_upgrade said that the old database is not in a very good condition, I would look for a problem in the database,
andnot something else.

pg_catalog.pg_indexes is a view. You can to modify pg_class to match
the pg_constraint name. You might be able to just rename the index in
Pgadmin to match.
Perhaps PGAdmin allowed this mismatch to happen?

It's not always been true that ALTER INDEX would try to rename
constraints to keep 'em in sync. A quick check says that only 8.3 and
later do that. I'm not sure though how a 9.0 database could get into
such a state without manual catalog hacking, since as you say a dump and
reload should have ended up with the index and constraint having the
same name again.
I'd be inclined not to worry about this in pg_upgrade, at least not till
we see a plausible scenario for the situation to arise without manual
catalog changes.
