As part of a migration from 8.0 to 8.1 i want to convert the data from
ASCII to UTF-8.
I dumped the database with pg_dump (8.0) and tried to convert it with
iconv, but it shows an error:
$ iconv -t ASCII -t UTF-8 fahstats_data.dump -o fahstats_data_utf-8.dump
iconv: illegal input sequence at position 71407864
That position contains the decimal value 233:
$ od -A d -j 71407864 -N 1 -t u1 fahstats_data.dump
71407864 233
71407865
I could use pg_dump -E in 8.1 but it is in another machine with ADSL
connection and the dump size is 1.8GB. It would take more than 12
hours.
How to install pg_dump 8.1 only? I tried to copy the executable and
the libs but it did not work.
from what you wrote it seems that your dump contains non-ascii characters...
probably somehow non-ascii data got into your database. like iso-8859-1
or iso-8859-15 or cp-1252 (if you are using western-european stuff).
in those encodings, 255 = é.
maybe you could try something like:
iconv -f ISO-8859-1 -t UTF-8 ....
please note that a conversion FROM these encodings always succeeds. so a
success does not mean that you guessed the charset correctly. you still
will havet to check manually if the resulting document contains the
correct data.
