Обсуждение: documentation udpates to pgupgrade.html

Hello,

just doing an upgrade form PostgreSQL 8.4.4 on Windows 2007 64bit to
PostgreSQL 9.0 64bit on the same system.

I am working along
http://developer.postgresql.org/pgdocs/postgres/pgupgrade.html

There is written:

NET STOP postgresql-8.4
NET STOP postgresql-9.0
or

NET STOP pgsql-8.3  (PostgreSQL 8.3 and older used a different service name)

which should be extended by

net stop postgresql-x64-9.0

for Windows 64 bit.

-----------------

It would also be helpfull, if there was a reamrk that pg_upgrade will
try to write to the current directory - as "runas /user:postgres
cmd.exe" usually starts within c:\windows\system; so a cd %TEMP% after
runas would be valuable

-----------------

Interesting.  What I have added to HEAD and 9.0 docs is the attached
patch that explains the proper service name should be used.  I don't
think I want to mention 64-bit explicitly, and in fact this section is
part of an 'e.g.' block, meaning they are just examples.  If I get more
64-bit reports I can add an example for that too.

Agreed.  Second patch attached that mentions this.

Can we document an easy way to find the service names?

Bruce,

To query for Postgresql services on Windows use:

sc query type= service | find "postgresql"


On my machine this yields:

SERVICE_NAME: postgresql-9.0
DISPLAY_NAME: postgresql-9.0 - PostgreSQL Server 9.0


NB the space after type= is very important, don't ask me why...



I prefer to use 'sc start <servicename>' and 'sc stop <servicename>',
then you can use one tool for everything.

The following shows these commands (and the query command) in action.


C:\Documents and Settings\Administrator>sc stop postgresql-9.0

SERVICE_NAME: postgresql-9.0       TYPE               : 10  WIN32_OWN_PROCESS       STATE              : 3
STOP_PENDING                              (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)       WIN32_EXIT_CODE    : 0  (0x0)
   SERVICE_EXIT_CODE  : 0  (0x0)       CHECKPOINT         : 0x2       WAIT_HINT          : 0x2710
 

C:\Documents and Settings\Administrator>sc start postgresql-9.0

SERVICE_NAME: postgresql-9.0       TYPE               : 10  WIN32_OWN_PROCESS       STATE              : 2
START_PENDING                              (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN))
 
       WIN32_EXIT_CODE    : 0  (0x0)       SERVICE_EXIT_CODE  : 0  (0x0)       CHECKPOINT         : 0x0       WAIT_HINT
        : 0x7d0       PID                : 3732       FLAGS              :
 

C:\Documents and Settings\Administrator>sc query postgresql-9.0

SERVICE_NAME: postgresql-9.0       TYPE               : 10  WIN32_OWN_PROCESS       STATE              : 4  RUNNING
                         (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)       WIN32_EXIT_CODE    : 0  (0x0)
SERVICE_EXIT_CODE : 0  (0x0)       CHECKPOINT         : 0x0       WAIT_HINT          : 0x0
 



Hope this isn't too much info and answers all your questions :-)

Colin

Oops.

Apparently type= service is the default, so we can remove that bit.

Then we should add state= all. The default = active, a third option = inactive.

So:

sc query state= all

should list all services, in all states.

And then we pipe to find which is the Windows equivalent of grep, but
it needs to have its parameter in double quotes.

So:

sc query state= all | find "postgresql"


Regards,

Colin
