Thread: copy
Hello. We are moving a database from informix to Postgresql. To do so we do an unload from Informix and copy to postgresql. Informix unloads with a delimiter also after the last field in a record. This is no problem when doing a copy to Postgresql 7.2 You get a warning (to many fields) but the copy process continues. In 7.4 however the copy stops . Does anyone know how to proceed the copy or a fast way to remove the last character from the unload files. They are anyhow to big to handle with vi. Many thanks Henk Sanders

cat <file> | sed '<delimiter>$//' > <file>.new
this should remove the last delimiter

Hello.
We are moving a database from informix to Postgresql.
To do so we do an unload from Informix and copy to postgresql.
Informix unloads with a delimiter also after the last field in a record.
This is no problem when doing a copy to Postgresql 7.2
You get a warning (to many fields) but the copy process continues.
In 7.4 however the copy stops .
Does anyone know how to proceed the copy or a fast way to remove the last
character
from the unload files.
They are anyhow to big to handle with vi.
Many thanks

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
fat fingered that one:
cat < file> | sed 's/<delimiter>$//'> <file>.new
