Operating system: linux - debian8 - amd64
Description:

Hello,

We are experiencing segfault during pg_restore.
The problem appear to be a mix with multiple jobs (-j option) and table Data
exclusion (-l option).
If we use 1 jobs and table exclusion => OK
if we use >=2 jobs without -l options => OK

We use a bash script every night to import prod database on dev
environnement.
Since this update from 9.5.7 to 9.5.8, those error appeared at the first
excluded table DATA.

Here is a sample database test where we have segfault.

-----------------------------------------
## shell commands

#create test database with some fake data
createdb test_import
/usr/lib/postgresql/9.5/bin/psql -c 'create table "aaa" as SELECT
generate_series(1,10000) AS id, md5(random()::text) AS descr;' test_import
/usr/lib/postgresql/9.5/bin/psql -c 'create table "bbb" as SELECT
generate_series(1,10000) AS id, md5(random()::text) AS descr;' test_import

#dump database
pg_dump -Fc test_import -f test_import.dump

#exclude some "table Data" from list
pg_restore -l test_import.dump | egrep -v 'TABLE DATA public ('"aaa"') ' >
test_dump.list

#import in new database
createdb test_import2
/usr/lib/postgresql/9.5/bin/pg_restore -v -Fc -L test_dump.list -j 5 -d
test_import2 test_import.dump
-----------------------------
