I am using PG 8.2.17 with UTF8 encoding.
"PostgreSQL 8.2.17 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 4.1.1
(Gentoo 4.1.1)"
One of my tables somehow has invalid characters in it:
> ERROR: invalid byte sequence for encoding "UTF8": 0xa9
> HINT: This error can also happen if the byte sequence does not match
> the encoding expected by the server, which is controlled by
> "client_encoding".
I have already manually found a number of the bad rows by running
queries with text functions (upper) between groups of IDs until I found
the specific bad row.
1) Is there a quicker way to get a list of all rows with invalid characters
2) Shouldn't the database prevent these rows from being entered in the
first place?
3) I have backups of this database (using -Fc) and I noticed that on
restore, this table is not restored because of this error. Is there a
way to fix the existing backups, or tell the restore to ignore bad rows
instead of erroring out the whole table?
Thanks
