Implicit conversion from string to timestamp
I have some generic code to which I pass a series of values to be inserted
into a PostgreSQL table which includes a field which is defined as a timestamp
and which I wish to populate with a string of the form
"yyyy-MM-dd hh:mm:ss.SSS". Under pg 8 and before this worked fine
but now with 8.1 I seem to be getting an exception which reads:-
ERROR: column "created" is of type timestamp without time zone but expression
is of type character varying
All this is done using JDBC (so I suppose it might be a JDBC error).
I know that a number of things were tightened up with 8.1, is this one of
them? Or should I be asking this on the JDBC list.
I had thought that passing strings into timestamps was acceptable.

Check the JDBC archives --- I think you're probably getting burnt by
some side effect of the changes they made to use parameterized queries.
You have to be a lot more honest now about informing the JDBC driver
what datatype your statement parameters really are.
