Thread: Can't connect to 6.5.2 server with 7.0.2 client

Can't connect to 6.5.2 server with 7.0.2 client

From
Forest Wilkinson
Date:
I was just about to give postgres 7.0.2 a try on my development machine,
but after installing it, I find that I can't connect to my 6.5.2
production servers.  The following error message is reported by both psql
and pgaccess, upon trying to connect:

ERROR:  MultiByte strings (MB) must be enabled to use this function

The connection then fails.  Is there some way around this, short of
upgrading all my production servers?

Cheers,

Forest

Recompile your 7.0.2 without --enable-multibyte option.

From
Danny
Date:
- Hello
- I had previous experience with Access and MySQL.

-Situation

- I am trying to create the equvilant of the following which is a mysql
command.

- Queston
- But I cannot figure out how to do this is postgresql

"mysql -u root -p mydb < mydb.dump"

- I was trying to create a test database using the following commands using a
very cliche example . This command works on mySQL and should be part of the
ANSI SQL standard


mydb=# INSERT INTO Customer (Customer_ID,Customer_Name,Customer_Address,Customer_Email)
mydb-# VALUES ('1','Danny Ho','99 Second Ave, Kingswood','dannyh@customer.com'),
mydb-# ('2','Randal Handel','54 Oxford Road, Cambridge','randalh@customer.com')
mydb-# ;

-and I get the following errors :

ERROR:  parser: parse error at or near ","

Looking forwrd to your feedback.,

I think:
psql -u somebody -d template1 < yourdb.dump
would work.

you can't insert two values at the same time, you would have to use two INSERT.

That's a static setting, then?  Oh, bother.  I was hoping the pg7 clients
would be smart enough to fall back as necessary, for connecting
non-multibyte servers.

Recompile your 7.0 libpq without MULTIBYTE support.

7.0 servers are less stiff-necked about this incompatibility, but that
won't help you with a 6.5 server...

PostgreSQL doesn't support this syntax (yet). You need to split it into
two INSERT commands.
