Umm, yeah. I was thinking about how to do that. pl/pgsql is not the best language to do that in. In any case I found a bug in the version I posted and also added a function that does: test=# select * from db_utf8_verify(); tab | fld | location ------+-----+---------- tbl1 | foo | (12,3) (1 row) It gives the table, field and ctid of any values that failed. It skips pg_catalog. It's also *really* slow for long strings. Just executing it on the pg_rewrite in the default installation takes forever. If someone really wanted this for a large database maybe they should recode it in C. http://svana.org/kleptog/pgsql/utf8_verify.sql Have a nice day, -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > Patent. n.
