encoding and since by default the encoding for postgres is UTF8 my doubt
is how can I restore the old database with no errors.

The encoding must match the collation, that's all. You don't say what
you are recovering, but pg_dump emits a "SET client_encoding=latin2",
right? In which case it should just work.

If it's something else you need to show us exactly what the error
message is.

If you want everything connecting to the database to think it's latin2,
do:

ALTER DATABASE foo SET client_encoding=latin2;

Hello,

Thanks for your quick replay, but I had other thing to do and I haven't
could check your hint before.

I started a new postgresql-8-3 installation. Set it up, ok

I have the idea to create the database and the role and then load the
pg_dump result from the other database. The old databse has encoding
LATIN2 so I try to create with this encoding and I get the message(*):
ERROR: la codificacion LATIN2 no coincide con la configuracion regional
del servidor es_es.UTF8
DETAIL: la configuracion regional LC_TYPE del servidor requiere la
codificacion UTF8

The command I try is:
postgres=# create database gestio_sl with template=template0 owner
webadmin encoding='latin2';

(*)That means more or less:
LATIN2 doesn't match with the regional configuration of the server
regional configuration requires UTF8 encoding

So, my question is how can i set the regional configuration of the
server to LATIN2

Thanks in advance.

Good luck!

My point was, the database does not have to be in LATIN2 (so remove
the encoding=latin2 part). If you leave the database in UTF-8 but do
the command I suggested

ALTER DATABASE foo SET client_encoding=latin2;

Then everything will work like it used to and you will be able to load
your dump without problems.

If you really truly want to change the encoding you have to
reinitialise the whole cluster. Delete the directory and reinitdb.
