Description:
I'm using a Postgresql on the backend with UTF8 db
The problem arises with texvc.

It looks like this dynamic SQL
SELECT math_outputhash,math_html_conservativeness,math_html,math_mathml FROM math WHERE math_inputhash = '��FP ���P�\x1e��\x13�� '
causes serious problem with postgres. I think that WHERE clause has to be rewritten from dynamic SQL to a query with MATH_INPUTHASH value as a parameter.
I looked through the code and can't see an easy way to do it nicely.

Here is an error page with error detalization

Warning: pg_query() [function.pg-query]: Query failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb3 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". in /var/www/mediawiki-1.10.0/includes/DatabasePostgres.php on line 496
