Error in executing plpgsql function

Hi Everyone,

I am newbie and writing a plpgsql function. I have included source
code here for function. When I execute this function where it finds a
row in table it works fine and gives expected output.

The problem is when I run this function by passing a parameter values
where row does not exist in table. I expect it to print message and
return false. Instead it disconnects from server and throughs lot of
errors in log file. Here is output from executing this function

====When row is found======

called from psql

test=# select func1('2');
NOTICE:  Value of ID  2
NOTICE:  Value of NDI1 
NOTICE:  Value of CSSG 5007
NOTICE:  Value of Interval Dischargefunc1 
-------t
(1 row)

======when row is not found=====


test=# select func1('99');
pqReadData() -- backend closed the channel unexpectedly.       This probably means the backend terminated abnormally
  before or while processing the request.
 
The connection to the server was lost. Attempting reset: Failed.
!#

=====also i see following errors in server logfile===
Server process (pid 21536) exited with status 139 at Fri Nov 30
22:28:57 2001
Terminating any active server processes...

Any idea what is happeing?
Appreciate any help?
BTW- where can I find good documentation on plpgsql functions?

TIA
