The following bug has been logged on the website:
Bug reference: 8257
Logged by: Lloyd Albin
Email address: lal...@fhcrc.org
PostgreSQL version: 9.2.4
Operating system: SUSE Linux (64-bit)
Description:
I have found the restore will fail when using pg_restore's -j option, with
more than one core, on a dump that contains a COMMENT INDEX.
I have tried this using both Postgres 9.0.12 & 9.2.4
I have created a test case that shows the problem.
Create a database called test_db.
CREATE DATABASE test_db
WITH OWNER = postgres
ENCODING = 'UTF8'
TEMPLATE = template0;
Run this next section to add the table, index, and index comment to the
test_db database.
CREATE TABLE public.tbl_test (
pkey TEXT NOT NULL,
CONSTRAINT tbl_test_pkey PRIMARY KEY(pkey)
);
COMMENT ON INDEX public.tbl_test_pkey
IS 'Index Comment';
Once this test database is created, create a backup of the database.
pg_dump -Fc test_db > test_db.dump
Drop the test database and now lets restore it.
pg_restore -C -j 3 -d postgres -Fc test_db.dump
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 2525; 0 0 COMMENT INDEX
tbl_test_pkey postgres
pg_restore: [archiver (db)] could not execute query: ERROR: relation
"tbl_test_pkey" does not exist
Command was: COMMENT ON INDEX tbl_test_pkey IS 'Index Comment';
pg_restore: [archiver] worker process failed: exit code 1
If you use -j 1 or skip the -j option the restore will restore without any
errors.
