Hi All,
We decide add support PostgreSQL database (now supporting only Oracle
database) to our product.
In Oracle we mapping Java BigDecimal to number(19, 2), in PostgreSQL to
numeric(19, 2).
If I store to BigDecimal column number without decimal, e.g. 3, than
Oracle JDBC driver return 3,
I was testing the ispell text search dictionary and it appears to be behaving as
if the ispell option allaffixes was set to on. This wasn't the case for the
original tsearch2 contrib module, and for the ispell program itself which
defaults to off.
So for example, if I create a simple

troubles. Self-contained example follows:
Thank you, fixed. The reason was in incorrect optimization of GIN scan: GIN

account a difference of scan's
Great, thank you!
I assume this one goes into 8.4.3, right?

Hola
Me gustaría saber si es posible devolver el tamaño de un campo de una
determinada tabla. Es decir, si yo defino por ejemplo un campo de tipo

el número de bytes máximo de ese campo??

I would like to move a table that is used to store images from mysql to

We store chart images in a mysql medium blob type.

Having 'external tables' lets us avoid the step of loading data from a
file into the table. We do not have to check whether a load job has run
successfully, whether the data in the table really corresponds to the data
in the file etc. It also lets us decide how many rejects can be allowed
