Description Brion Vibber 2004-09-07 08:38:44 UTC
On a PostgreSQL-backed wiki, rendering <math> segments fails when trying to record the equation into the math table:

Warning: pg_query() []: Query failed: ERROR: null value in column "math_html" violates not-null constraint in /
var/www/html/gres/includes/DatabasePostgreSQL.php on line 96
A database error has occurred Query: INSERT INTO math 
(math_inputhash,math_outputhash,math_html_conservativeness,math_html,math_mathml) VALUES ('?0?????\\??:

Comment 1 Domas Mituzas 2004-09-07 13:46:30 UTC
fixed in current schema, 

alter table math alter column math_mathml drop not null;
alter table math alter column math_html drop not null;

those 'not nulls' suck anyway, if field can be null, why shouldn't it?
