Hi,

Wondering if this rings a bell with anyone. I have some tables with a few 
million rows each. It's all speedy enough unless I have a computed column 
(for example VARCHAR(5) AS (SELECT ... FROM indexed_relation...). To begin 
with, if I add an extra million rows to a table that has no computed 
column, the operation only takes a few seconds. If I then add a computed 
column to that table, for example a computed column that selects on a 
related table (using PK), the 'alter table' takes a few seconds. So there 
is no problem with the computed select column per se. But then, if I insert 
another million rows, the operation takes hours (if it ever finishes at 
all...). So inserting rows when there is an existing computed select column 
is unusably problematic. Just thought someone else might have definitely or 
definitely NOT experienced this same issue. It's consistent for H2 1.2 as 
well as 1.3. (I'll try to file a test case and bug report in the next few 
days, but have to get other things done to meet a deadline, having lost a 
whole afternoon and most of today to tracing this issue.)
