Обсуждение: org.postgresql.PG_Stream.ReceiveChar(PG_Stream.java:143)

Hi,
I have been using SOFIA framework and postgres
database as a backend.
i noticed as the database started growing larger..
today
encountered some error while firing a query to save a
record. The table in which i am going to save the
record, has two columns having datatype text. the data
of these two column contains 2652 and 5817 characters.
If I reduce some characters from both columns, it
saves the record successfully. But i reduce some
characters from only single column(whether it has 2652
chars or 5817 chars whereas both have the same
datatype), it gives me the following error :--

This looks like it could be a server crash.  Does the server's log show 
anything informative?  Also you don't mention what server and JDBC driver 
version you are using, but the stacktrace tells me the driver must be from 
the 7.2 or earlier release.  If the server log doesn't reveal anything you 
might try upgrading the JDBC driver to a later version.
