Hi,

Can anyone tell me where to find out information about going from 6.3 to 6.5? I have used the "\copy name to name" command to save all of the data to a file. I now want to import this data in 6.5. Any suggestions?

Export old database:

pg_dump -d dabasename -D database.sql

This will output the SQL commands to recreate all your tables and data. Then
import it into the new database:

psql < database.sql

Here is a simple way to import a tab delimited.

cat file.tab | psql -c "copy table1 from stdin;" database1

And now for a comma delimited file.

cat file.cvs | psql -c "copy table1 from stdin using delimiters ``,'';"
database1

CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION
CAUTION CAUTION
CAUTION make sure their are NO SINGLE '\' characters CAUTION
CAUTION CAUTION
CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION

The ``\'' character is an escape character.

To fix this automatically use a sed command like this.

sed -e "s;\\\;\\\\\\\;g" file.tab | sql -c "copy table1 from stdin;"
database1

You will also need to make sure any caracter in your data that is also
your
delimiter is escaped. For tabs escape tabs in the data with ``\ ''.
For comma's escape with ``\,''.

Escaping tabs can be difficult using a bash shell, you can do it within
a script.

This works for me.
