Re: pg_upgrade in 9.3.5 can not start cluster - Mailing list pgsql-pkg-debian

We have finally found out why this happens, it's probably a slight issue in argument handling in pg_upgrade. When we
runthe upgrade command in this form:
 

/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.2/bin -B /usr/lib/postgresql/9.3/bin -d
/var/lib/postgresql/9.2/main/-D /var/lib/postgresql/9.3/main/ -O "-c
config_file=/etc/postgresql/9.3/main/postgresql.conf"-o "-c config_file=/etc/postgresql/9.2/main/postgresql.conf"
 

Cluster startup fails on 

could not connect to new postmaster started with the command:
"/usr/lib/postgresql/9.3/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/var/lib/postgresql/9.3/main/" -o "-p 50432 -b
-cautovacuum_multixact_freeze_max_age=2000000000  -c synchronous_commit=off -c fsync=off -c full_page_writes=off-c
config_file=/etc/postgresql/9.3/main/postgresql.conf-c listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/var/lib/postgresql'"start
 
Failure, exiting

When we issue the upgrade command with additional spaces before config_file options (both -O and -o), all works as
expectedand upgrade works flawlessly. 
 

/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.2/bin -B /usr/lib/postgresql/9.3/bin -d
/var/lib/postgresql/9.2/main/-D /var/lib/postgresql/9.3/main/ -O " -c
config_file=/etc/postgresql/9.3/main/postgresql.conf"-o " -c config_file=/etc/postgresql/9.2/main/postgresql.conf"
 

I am pretty sure that the command without space worked before and now it doesn't, we haven't changed our upgrade guide
formonths.

Actually, we don't... I have managed another clean environment, so we will try the same process with the same
configurationagain and I'll let you know.

9.3.It seems to be a typo somewhere in the source code. Unfortunately, I don't have the logs anymore, but the problem
wasthat pg_upgrade refused to start cluster with an error that went like 'parameter "full_page_writes" requires a
Booleanvalue'. The problem was that the startup command had a typo in it and contained '-c full_page_writes=off-c
anotherparameter...'(Notice no space after =off).

It's not reproducible on a clean Debian box.

Do you have full_page_writes mentioned in /etc/postgresql/9.2/main/pg_ctl.conf or the like?
